Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Discard command completions in internal error
Fix use after free when FW completion arrives while device is in
internal error state. Avoid calling completion handler in this case,
since the device will flush the command interface and trigger all
completions manually.
Kernel log:
------------[ cut here ]------------
refcount_t: underflow; use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: Fix null dereference on suspend
A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.
Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
called which dereferences cur_msg (which is now NULL)
Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix kernel crash problem in concurrent scenario
When link status change, the nic driver need to notify the roce
driver to handle this event, but at this time, the roce driver
may uninit, then cause kernel crash.
To fix the problem, when link status change, need to check
whether the roce registered, and when uninit, need to wait link
update finish.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Synchronize devfreq_monitor_[start/stop]
There is a chance if a frequent switch of the governor
done in a loop result in timer list corruption where
timer cancel being done from two place one from
cancel_delayed_work_sync() and followed by expire_timers()
can be seen from the traces[1].
while true
do
echo "simple_ondemand" > /sys/class/devfreq/1d84000.ufshc/governor
echo "performance" > /sys/class/devfreq/1d84000.ufshc/governor
done
It looks to be issue with devfreq driver where
device_monitor_[start/stop] need to synchronized so that
delayed work should get corrupted while it is either
being queued or running or being cancelled.
Let's use polling flag and devfreq lock to synchronize the
queueing the timer instance twice and work data being
corrupted.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/proc: do_task_stat: use sig->stats_lock to gather the threads/children stats
lock_task_sighand() can trigger a hard lockup. If NR_CPUS threads call
do_task_stat() at the same time and the process has NR_THREADS, it will
spin with irqs disabled O(NR_CPUS * NR_THREADS) time.
Change do_task_stat() to use sig->stats_lock to gather the statistics
outside of ->siglock protected section, in the likely case this code will
run lockless.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout
There is a race condition between l2cap_chan_timeout() and
l2cap_chan_del(). When we use l2cap_chan_del() to delete the
channel, the chan->conn will be set to null. But the conn could
be dereferenced again in the mutex_lock() of l2cap_chan_timeout().
As a result the null pointer dereference bug will happen. The
KASAN report triggered by POC is shown below:

When we use l2cap_chan_del() to delete the\nchannel, the chan-\u003econn will be set to null. But the conn could\nbe dereferenced again in the mutex_lock() of l2cap_chan_timeout().\nAs a result the null pointer dereference bug will happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Fix invalid reads in fence signaled events
Correctly set the length of the drm_event to the size of the structure
that's actually used.
The length of the drm_event was set to the parent structure instead of
to the drm_vmw_event_fence which is supposed to be read. drm_read
uses the length parameter to copy the event to the user space thus
resuling in oob reads.

There is no network-facing path to this code.\nAC:L - Exploitation is fully deterministic \u2014 a single ioctl followed by a read reliably copies 72 bytes past the end of the allocation, with no race, no timing window, and no attacker-uncontrolled precondition. Heap grooming of the kmalloc-96 cache to control the leaked neighbour is standard and repeatable at will.\nPR:L - The ioctl is marked DRM_RENDER_ALLOW, so it is served on the render node which is world-accessible (0666 or group \"render\") on typical VMware guest desktop/workstation installs \u2014 no DRM master, DRM_AUTH, or capability check is applied. Any unprivileged local user with a graphics session or render-node access can reach it.\nUI:N - The attacker opens its own DRM fd, issues the ioctl and reads the event entirely within its own process. No victim action or interaction of any kind is required.\nS:U - The leaked data is guest kernel heap memory disclosed to guest userspace, and any resulting crash is confined to the same kernel. The vulnerable component and the impacted resources share one security authority; there is no guest-to-host or IOMMU boundary crossing.\nC:H - 72 bytes of adjacent kernel slab memory are copied verbatim to userspace on every event read, and the attacker can groom the kmalloc-96 cache and repeat the read indefinitely to harvest kernel pointers, SLUB freelist values and residual object contents. This is a substantial, repeatable kernel heap information disclosure enabling KASLR/heap-address defeat, not a strictly bounded few-byte read.\nI:N - The defect is purely an over-long read; no data is written out of bounds and the inflated length is applied symmetrically to the event_space reserve/release accounting, so no kernel state is corrupted. There is no write or control-flow primitive.\nA:H - On the many distro and Android kernels built with CONFIG_HARDENED_USERCOPY=y, __check_heap_object() rejects the 96-byte copy starting at offset 72 of a 96-byte object and calls usercopy_abort(), which invokes BUG() \u2014 an unprivileged local user can therefore force a kernel oops (or full panic with panic_on_oops) on demand."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp_metrics: validate source addr length
I don't see anything checking that TCP_METRICS_ATTR_SADDR_IPV4
is at least 4 bytes long, and the policy doesn't have an entry
for this attribute at all (neither does it for IPv6 but v6 is
manually validated).

Summary
In the Linux kernel, the following vulnerability has been resolved:
pstore/ram: Fix crash when setting number of cpus to an odd number
When the number of cpu cores is adjusted to 7 or other odd numbers,
the zone size will become an odd number.
The address of the zone will become:
addr of zone0 = BASE
addr of zone1 = BASE + zone_size
addr of zone2 = BASE + zone_size*2
...
The address of zone1/3/5/7 will be mapped to non-alignment va.
Eventually crashes will occur when accessing these va.
So, use ALIGN_DOWN() to make sure the zone size is even
to avoid this bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix illegal rmb_desc access in SMC-D connection dump
A crash was found when dumping SMC-D connections. It can be reproduced
by following steps:
- run nginx/wrk test:
smc_run nginx
smc_run wrk -t 16 -c 1000 -d <duration> -H 'Connection: Close' <URL>
- continuously dump SMC-D connections in parallel:
watch -n 1 'smcss -D'
BUG: kernel NULL pointer dereference, address: 0000000000000030
CPU: 2 PID: 7204 Comm: smcss Kdump: loaded Tainted: G E 6.7.0+ #55

It is possible that the connection is in process of being established
when we dump it. Assumed that the connection has been registered in a
link group by smc_conn_create() but the rmb_desc has not yet been
initialized by smc_buf_create(), thus causing the illegal access to
conn->rmb_desc. So fix it by checking before dump.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: avoid data corruption caused by decline
We found a data corruption issue during testing of SMC-R on Redis
applications.
The benchmark has a low probability of reporting a strange error as
shown below.
"Error: Protocol error, got "\xe2" as reply type byte"
Finally, we found that the retrieved error data was as follows:
0xE2 0xD4 0xC3 0xD9 0x04 0x00 0x2C 0x20 0xA6 0x56 0x00 0x16 0x3E 0x0C
0xCB 0x04 0x02 0x01 0x00 0x00 0x20 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xE2
It is quite obvious that this is a SMC DECLINE message, which means that
the applications received SMC protocol message.
We found that this was caused by the following situations:
client server
¦ clc proposal
------------->
¦ clc accept
<-------------
¦ clc confirm
------------->
wait llc confirm
send llc confirm
¦failed llc confirm
¦ x------
(after 2s)timeout
wait llc confirm rsp
wait decline
(after 1s) timeout
(after 2s) timeout
¦ decline
-------------->
¦ decline
<--------------
As a result, a decline message was sent in the implementation, and this
message was read from TCP by the already-fallback connection.
This patch double the client timeout as 2x of the server value,
With this simple change, the Decline messages should never cross or
collide (during Confirm link timeout).
This issue requires an immediate solution, since the protocol updates
involve a more long-term solution.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: avoid using null object of framebuffer
Instead of using state->fb->obj[0] directly, get object from framebuffer
by calling drm_gem_fb_get_obj() and return error code when object is
null to avoid using null object of framebuffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Return error if block header overflows file
Return an error from cs_dsp_power_up() if a block header is longer
than the amount of data left in the file.
The previous code in cs_dsp_load() and cs_dsp_load_coeff() would loop
while there was enough data left in the file for a valid region. This
protected against overrunning the end of the file data, but it didn't
abort the file processing with an error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Use strnlen() on name fields in V1 wmfw files
Use strnlen() instead of strlen() on the algorithm and coefficient name
string arrays in V1 wmfw files.
In V1 wmfw files the name is a NUL-terminated string in a fixed-size
array. cs_dsp should protect against overrunning the array if the NUL
terminator is missing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray
Patch series "mm/filemap: Limit page cache size to that supported by
xarray", v2.
Currently, xarray can't support arbitrary page cache size. More details
can be found from the WARN_ON() statement in xas_split_alloc(). In our
test whose code is attached below, we hit the WARN_ON() on ARM64 system
where the base page size is 64KB and huge page size is 512MB. The issue
was reported long time ago and some discussions on it can be found here
[1].
[1] https://www.spinics.net/lists/linux-xfs/msg75404.html
In order to fix the issue, we need to adjust MAX_PAGECACHE_ORDER to one
supported by xarray and avoid PMD-sized page cache if needed. The code
changes are suggested by David Hildenbrand.
PATCH[1] adjusts MAX_PAGECACHE_ORDER to that supported by xarray
PATCH[2-3] avoids PMD-sized page cache in the synchronous readahead path
PATCH[4] avoids PMD-sized page cache for shmem files if needed

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Avoid memcpy field-spanning write WARNING
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver
prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)
WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8
replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended
to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array
declaration and clarify that it has flexible length. Also, adjust the
memory allocation size to match the change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/qeth: Fix kernel panic after setting hsuid
Symptom:
When the hsuid attribute is set for the first time on an IQD Layer3
device while the corresponding network interface is already UP,
the kernel will try to execute a napi function pointer that is NULL.

[ 2057.572847] Kernel panic - not syncing: Fatal exception in interrupt
-------------------------------------------------------------------------------------------
Analysis:
There is one napi structure per out_q: card->qdio.out_qs[i].napi
The napi.poll functions are set during qeth_open().
Since
commit 1cfef80d4c2b ("s390/qeth: Don't call dev_close/dev_open (DOWN/UP)")
qeth_set_offline()/qeth_set_online() no longer call dev_close()/
dev_open(). So if qeth_free_qdio_queues() cleared
card->qdio.out_qs[i].napi.poll while the network interface was UP and the
card was offline, they are not set again.
Reproduction:
chzdev -e $devno layer2=0
ip link set dev $network_interface up
echo 0 > /sys/bus/ccw

Summary
In the Linux kernel, the following vulnerability has been resolved:
of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix overrunning reservations in ringbuf
The BPF ring buffer internally is implemented as a power-of-2 sized circular
buffer, with two logical and ever-increasing counters: consumer_pos is the
consumer counter to show which logical position the consumer consumed the
data, and producer_pos which is the producer counter denoting the amount of
data reserved by all producers.
Each time a record is reserved, the producer that "owns" the record will
successfully advance producer counter. In user space each time a record is
read, the consumer of the data advanced the consumer counter once it finished
processing. Both counters are stored in separate pages so that from user
space, the producer counter is read-only and the consumer counter is read-write.
One aspect that simplifies and thus speeds up the implementation of both
producers and consumers is how the data area is mapped twice contiguously
back-to-back in the virtual memory, allowing to not take any special measures
for samples that have to wrap around at the end of the circular buffer data
area, because the next page after the last data page would be first data page
again, and thus the sample will still appear completely contiguous in virtual
memory.
Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
book-keeping the length and offset, and is inaccessible to the BPF program.
Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
possible to make a second allocated memory chunk overlapping with the first
chunk and as a result, the BPF program is now able to edit first chunk's
header.
For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
allocate a chunk B with size 0x3000. This will succeed because consumer_pos
was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
page and could cause a crash.
Fix it by calculating the oldest pending_pos and check whether the range
from the oldest outstanding record to the newest would span beyond the ring
buffer size. If that is the case, then reject the request. We've tested with
the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
before/after the fix and while it seems a bit slower on some benchmarks, it
is still not significantly enough to matter.

Due to the ring buffer memory layout mentioned\nearlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data\npages. This means that chunk B at [0x4000,0x4008] is chunk A\u0027s header.\nbpf_ringbuf_submit() / bpf_ringbuf_discard() use the header\u0027s pg_off to then\nlocate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk\nB modified chunk A\u0027s header, then bpf_ringbuf_commit() refers to the wrong\npage and could cause a crash.\n\nFix it by calculating the oldest pending_pos and check whether the range\nfrom the oldest outstanding record to the newest would span beyond the ring\nbuffer size. If that is the case, then reject the request. We\u0027ve tested with\nthe ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)\nbefore/after the fix and while it seems a bit slower on some benchmarks, it\nis still not significantly enough to matter."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc
Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001.
V2: To really improve the handling we would actually
need to have a separate value of 0xffffffff.(Christian)

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: initialize integrity buffer to zero before writing it to media
Metadata added by bio_integrity_prep is using plain kmalloc, which leads
to random kernel memory being written media. For PI metadata this is
limited to the app tag that isn't used by kernel generated metadata,
but for non-PI metadata the entire buffer leaks kernel memory.
Fix this by adding the __GFP_ZERO flag to allocations for writes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nouveau: fix instmem race condition around ptr stores
Running a lot of VK CTS in parallel against nouveau, once every
few hours you might see something like this crash.

Adding any sort of useful debug usually makes it go away, so I hand
wrote the function in a line, and debugged the asm.
Every so often pt->memory->ptrs is NULL. This ptrs ptr is set in
the nv50_instobj_acquire called from nvkm_kmap.
If Thread A and Thread B both get to nv50_instobj_acquire around
the same time, and Thread A hits the refcount_set line, and in
lockstep thread B succeeds at refcount_inc_not_zero, there is a
chance the ptrs value won't have been stored since refcount_set
is unordered. Force a memory barrier here, I picked smp_mb, since
we want it on all CPUs and it's write followed by a read.
v2: use paired smp_rmb/smp_wmb.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/iucv: fix use after free in iucv_sock_close()
iucv_sever_path() is called from process context and from bh context.
iucv->path is used as indicator whether somebody else is taking care of
severing the path (or it is already removed / never existed).
This needs to be done with atomic compare and swap, otherwise there is a
small window where iucv_sock_close() will try to work with a path that has
already been severed and freed by iucv_callback_connrej() called by
iucv_tasklet_fn().
Example:
[452744.123844] Call Trace:

[452744.125324]
[452744.125325] Kernel panic - not syncing: Fatal exception in interrupt
Note that bh_lock_sock() is not serializing the tasklet context against
process context, because the check for sock_owned_by_user() and
corresponding handling is missing.
Ideas for a future clean-up patch:
A) Correct usage of bh_lock_sock() in tasklet context, as described in
Re-enqueue, if needed. This may require adding return values to the
tasklet functions and thus changes to all users of iucv.
B) Change iucv tasklet into worker and use only lock_sock() in af_iucv.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix shift-out-of-bounds in dctcp_update_alpha().
In dctcp_update_alpha(), we use a module parameter dctcp_shift_g
as follows:
alpha -= min_not_zero(alpha, alpha >> dctcp_shift_g);
...
delivered_ce <<= (10 - dctcp_shift_g);
It seems syzkaller started fuzzing module parameters and triggered
shift-out-of-bounds [0] by setting 100 to dctcp_shift_g:
memcpy((void*)0x20000080,
"/sys/module/tcp_dctcp/parameters/dctcp_shift_g\000", 47);
res = syscall(__NR_openat, /*fd=*/0xffffffffffffff9cul, /*file=*/0x20000080ul,
/*flags=*/2ul, /*mode=*/0ul);
memcpy((void*)0x20000000, "100\000", 4);
syscall(__NR_write, /*fd=*/r[0], /*val=*/0x20000000ul, /*len=*/4ul);
Let's limit the max value of dctcp_shift_g by param_set_uint_minmax().
With this patch:
# echo 10 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
# cat /sys/module/tcp_dctcp/parameters/dctcp_shift_g
10
# echo 11 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
-bash: echo: write error: Invalid argument
[0]:
UBSAN: shift-out-of-bounds in net/ipv4/tcp_dctcp.c:143:12

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: do not accept ACK of bytes we never sent
This patch is based on a detailed report and ideas from Yepeng Pan
and Christian Rossow.
ACK seq validation is currently following RFC 5961 5.2 guidelines:
The ACK value is considered acceptable only if
it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <=
SND.NXT). All incoming segments whose ACK value doesn't satisfy the
above condition MUST be discarded and an ACK sent back. It needs to
be noted that RFC 793 on page 72 (fifth check) says: "If the ACK is a
duplicate (SEG.ACK < SND.UNA), it can be ignored. If the ACK
acknowledges something not yet sent (SEG.ACK > SND.NXT) then send an
ACK, drop the segment, and return". The "ignored" above implies that
the processing of the incoming data segment continues, which means
the ACK value is treated as acceptable. This mitigation makes the
ACK check more stringent since any ACK < SND.UNA wouldn't be
accepted, instead only ACKs that are in the range ((SND.UNA -
MAX.SND.WND) <= SEG.ACK <= SND.NXT) get through.
This can be refined for new (and possibly spoofed) flows,
by not accepting ACK for bytes that were never sent.
This greatly improves TCP security at a little cost.
I added a Fixes: tag to make sure this patch will reach stable trees,
even if the 'blamed' patch was adhering to the RFC.
tp->bytes_acked was added in linux-4.2
Following packetdrill test (courtesy of Yepeng Pan) shows
the issue at hand:
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0 bind(3, ..., ...) = 0
+0 listen(3, 1024) = 0
// ---------------- Handshake ------------------- //
// when window scale is set to 14 the window size can be extended to
// 65535 * (2^14) = 1073725440. Linux would accept an ACK packet
// with ack number in (Server_ISN+1-1073725440. Server_ISN+1)
// ,though this ack number acknowledges some data never
// sent by the server.
+0 < S 0:0(0) win 65535 <mss 1400,nop,wscale 14>
+0 > S. 0:0(0) ack 1 <...>
+0 < . 1:1(0) ack 1 win 65535
+0 accept(3, ..., ...) = 4
// For the established connection, we send an ACK packet,
// the ack packet uses ack number 1 - 1073725300 + 2^32,
// where 2^32 is used to wrap around.
// Note: we used 1073725300 instead of 1073725440 to avoid possible
// edge cases.
// 1 - 1073725300 + 2^32 = 3221241997
// Oops, old kernels happily accept this packet.
+0 < . 1:1001(1000) ack 3221241997 win 65535
// After the kernel fix the following will be replaced by a challenge ACK,
// and prior malicious frame would be dropped.
+0 > . 1:1(0) ack 1001

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: do not accept ACK of bytes we never sent\n\nThis patch is based on a detailed report and ideas from Yepeng Pan\nand Christian Rossow.\n\nACK seq validation is currently following RFC 5961 5.2 guidelines:\n\n The ACK value is considered acceptable only if\n it is in the range of ((SND.UNA - MAX.SND.WND) \u003c= SEG.ACK \u003c=\n SND.NXT). All incoming segments whose ACK value doesn\u0027t satisfy the\n above condition MUST be discarded and an ACK sent back. It needs to\n be noted that RFC 793 on page 72 (fifth check) says: \"If the ACK is a\n duplicate (SEG.ACK \u003c SND.UNA), it can be ignored. If the ACK\n acknowledges something not yet sent (SEG.ACK \u003e SND.NXT) then send an\n ACK, drop the segment, and return\". The \"ignored\" above implies that\n the processing of the incoming data segment continues, which means\n the ACK value is treated as acceptable. This mitigation makes the\n ACK check more stringent since any ACK \u003c SND.UNA wouldn\u0027t be\n accepted, instead only ACKs that are in the range ((SND.UNA -\n MAX.SND.WND) \u003c= SEG.ACK \u003c= SND.NXT) get through.\n\nThis can be refined for new (and possibly spoofed) flows,\nby not accepting ACK for bytes that were never sent.\n\nThis greatly improves TCP security at a little cost.\n\nI added a Fixes: tag to make sure this patch will reach stable trees,\neven if the \u0027blamed\u0027 patch was adhering to the RFC.\n\ntp-\u003ebytes_acked was added in linux-4.2\n\nFollowing packetdrill test (courtesy of Yepeng Pan) shows\nthe issue at hand:\n\n0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3\n+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0\n+0 bind(3, ..., ...) = 0\n+0 listen(3, 1024) = 0\n\n// ---------------- Handshake ------------------- //\n\n// when window scale is set to 14 the window size can be extended to\n// 65535 * (2^14) = 1073725440.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Validate payload length before processing block
Move the payload length check in cs_dsp_load() and cs_dsp_coeff_load()
to be done before the block is processed.
The check that the length of a block payload does not exceed the number
of remaining bytes in the firwmware file buffer was being done near the
end of the loop iteration. However, some code before that check used the
length field without validating it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mos7840: fix crash on resume
Since commit c49cfa917025 ("USB: serial: use generic method if no
alternative is provided in usb serial layer"), USB serial core calls the
generic resume implementation when the driver has not provided one.
This can trigger a crash on resume with mos7840 since support for
multiple read URBs was added back in 2011. Specifically, both port read
URBs are now submitted on resume for open ports, but the context pointer
of the second URB is left set to the core rather than mos7840 port
structure.
Fix this by implementing dedicated suspend and resume functions for
mos7840.
Tested with Delock 87414 USB 2.0 to 4x serial adapter.
[ johan: analyse crash and rewrite commit message; set busy flag on
resume; drop bulk-in check; drop unnecessary usb_kill_urb() ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix double-free of blocks due to wrong extents moved_len
In ext4_move_extents(), moved_len is only updated when all moves are
successfully executed, and only discards orig_inode and donor_inode
preallocations when moved_len is not zero. When the loop fails to exit
after successfully moving some extents, moved_len is not updated and
remains at 0, so it does not discard the preallocations.
If the moved extents overlap with the preallocated extents, the
overlapped extents are freed twice in ext4_mb_release_inode_pa() and
ext4_process_freed_data() (as described in commit 94d7c16cbbbd ("ext4:
Fix double-free of blocks with EXT4_IOC_MOVE_EXT")), and bb_free is
incremented twice. Hence when trim is executed, a zero-division bug is
triggered in mb_update_avg_fragment_size() because bb_free is not zero
and bb_fragments is zero.
Therefore, update move_len after each extent move to avoid the issue.

No victim action is needed, since the target ext4 filesystem is already mounted on any normal system.\nS:U - The double free, bitmap corruption, and divide-error oops all occur within the kernel\u0027s own security authority on the same host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The double free returns blocks that are still referenced by a live inode to the free-space bitmap, so they can be reallocated into an attacker-controlled file, exposing another user\u0027s file contents through cross-file block aliasing. This is an unbounded read of arbitrary on-disk data belonging to other users.\nI:H - The same block aliasing lets the attacker overwrite data blocks still owned by another inode, and mb_free_blocks() additionally marks the group bitmap corrupt while inflating bb_free, leaving persistent allocator and on-disk metadata corruption. That is arbitrary modification of other users\u0027 file data and of filesystem metadata.\nA:H - The inconsistent bb_free/bb_fragments state causes a divide-by-zero oops in mb_update_avg_fragment_size() while ext4_lock_group() is held, so the group spinlock is orphaned and subsequent accesses deadlock. Even short of that, ext4_grp_locked_error() forces the filesystem read-only under the default errors=remount-ro, or panics the kernel under errors=panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
vt_ioctl: fix array_index_nospec in vt_setactivate
array_index_nospec ensures that an out-of-bounds value is set to zero
on the transient path. Decreasing the value by one afterwards causes
a transient integer underflow. vsa.console should be decreased first
and then sanitized with array_index_nospec.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfs: add bounds checking to xlog_recover_process_data
There is a lack of verification of the space occupied by fixed members
of xlog_op_header in the xlog_recover_process_data.
We can create a crafted image to trigger an out of bounds read by
following these steps:
1) Mount an image of xfs, and do some file operations to leave records
2) Before umounting, copy the image for subsequent steps to simulate
abnormal exit. Because umount will ensure that tail_blk and
head_blk are the same, which will result in the inability to enter
xlog_recover_process_data
3) Write a tool to parse and modify the copied image in step 2
4) Make the end of the xlog_op_header entries only 1 byte away from
xlog_rec_header->h_size
5) xlog_rec_header->h_num_logops++
6) Modify xlog_rec_header->h_crc
Fix:
Add a check to make sure there is sufficient space to access fixed members
of xlog_op_header.

There is no network-facing path to `xlog_recover_process_data()`.\nAC:L - The attacker fully controls the on-disk log: placing the final `xlog_op_header` one byte short of `h_len`, incrementing `h_num_logops`, and recomputing `h_crc` makes the overrun fire deterministically on every mount, with no race or memory-layout condition outside attacker control.\nPR:N - The attacker needs no account or privilege on the target system \u2014 they only supply the malicious image (e.g. a USB stick or disk image), and the mount is performed by the victim or by an automounter such as udisks2/systemd on a desktop or kiosk.\nUI:R - Exploitation requires a separate party to mount the crafted XFS filesystem, since `xfs_fs_type` lacks `FS_USERNS_MOUNT` and mounting needs CAP_SYS_ADMIN in the initial user namespace or an automounter acting for a physically present user.\nS:U - The out-of-bounds read and its consequences are confined to the kernel\u0027s own memory and the mounting kernel\u0027s security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 11 bytes of kernel heap memory adjacent to the `kvzalloc()`ed log buffer are read out of bounds, and `xlog_recover_process_ophdr()` then emits those bytes into the kernel log via `xfs_warn(\"bad clientid 0x%x\")`/`(\"bad length 0x%x\")`, disclosing adjacent heap contents.\nI:N - There is no out-of-bounds write, and because `dp \u003e end` after the overrun the `dp + len \u003e end` check in `xlog_recover_process_ophdr()` unconditionally returns `-EFSCORRUPTED` before any of the OOB-derived values (`oh_tid`, `oh_flags`) are used, so no kernel or filesystem state is modified.\nA:H - If the log buffer came from the `kvzalloc()` vmalloc fallback, the read crosses into the guard page and oopses the mounting task with recovery locks held; additionally the path executes `WARN_ON(1)` (panic on `panic_on_warn` systems) and `ASSERT(0)`/`ASSERT(dp \u003c= end)` panics on `CONFIG_XFS_ASSERT_FATAL` builds."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bonding: fix xfrm real_dev null pointer dereference
We shouldn't set real_dev to NULL because packets can be in transit and
xfrm might call xdo_dev_offload_ok() in parallel. All callbacks assume
real_dev is set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ibmvfc: Remove BUG_ON in the case of an empty event pool
In practice the driver should never send more commands than are allocated
to a queue's event pool. In the unlikely event that this happens, the code
asserts a BUG_ON, and in the case that the kernel is not configured to
crash on panic returns a junk event pointer from the empty event list
causing things to spiral from there. This BUG_ON is a historical artifact
of the ibmvfc driver first being upstreamed, and it is well known now that
the use of BUG_ON is bad practice except in the most unrecoverable
scenario. There is nothing about this scenario that prevents the driver
from recovering and carrying on.
Remove the BUG_ON in question from ibmvfc_get_event() and return a NULL
pointer in the case of an empty event pool. Update all call sites to
ibmvfc_get_event() to check for a NULL pointer and perfrom the appropriate
failure or recovery action.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/bhi: Avoid warning in #DB handler due to BHI mitigation
When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set
then entry_SYSENTER_compat() uses CLEAR_BRANCH_HISTORY and calls the
clear_bhb_loop() before the TF flag is cleared. This causes the #DB handler
(exc_debug_kernel()) to issue a warning because single-step is used outside the
entry_SYSENTER_compat() function.
To address this issue, entry_SYSENTER_compat() should use CLEAR_BRANCH_HISTORY
after making sure the TF flag is cleared.
The problem can be reproduced with the following sequence:
$ cat sysenter_step.c
int main()
{ asm("pushf; pop %ax; bts $8,%ax; push %ax; popf; sysenter"); }
$ gcc -o sysenter_step sysenter_step.c
$ ./sysenter_step
Segmentation fault (core dumped)
The program is expected to crash, and the #DB handler will issue a warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: regenerate buddy after block freeing failed if under fc replay
This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant
mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on
code in mb_free_blocks(), fast commit replay can end up marking as free
blocks that are already marked as such. This causes corruption of the
buddy bitmap so we need to regenerate it in that case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: avoid too many retransmit packets
If a TCP socket is using TCP_USER_TIMEOUT, and the other peer
retracted its window to zero, tcp_retransmit_timer() can
retransmit a packet every two jiffies (2 ms for HZ=1000),
for about 4 minutes after TCP_USER_TIMEOUT has 'expired'.
The fix is to make sure tcp_rtx_probe0_timed_out() takes
icsk->icsk_user_timeout into account.
Before blamed commit, the socket would not timeout after
icsk->icsk_user_timeout, but would use standard exponential
backoff for the retransmits.
Also worth noting that before commit e89688e3e978 ("net: tcp:
fix unexcepted socket die when snd_wnd is 0"), the issue
would last 2 minutes instead of 4.

Any remote TCP peer of a socket with TCP_USER_TIMEOUT set (NFS client transports, ocfs2, BPF-sockops-configured connections, gRPC/Envoy/HAProxy/Redis servers) can trigger it.\nAC:L - The attacker fully controls the trigger \u2014 shrink the receive window to zero (stop reading, or use a custom stack) and keep ACKing the zero-window probes to keep tp-\u003ercv_tstamp fresh so tcp_rtx_probe0_timed_out() never aborts. No race, timing luck, or memory-layout dependency; TCP_USER_TIMEOUT being set is a common attacker-independent deployment property (sunrpc sets it unconditionally), i.e. part of the vulnerable configuration.\nPR:N - No authentication or credentials are required \u2014 establishing a TCP connection and getting unacked data in flight (e.g. a banner or a pre-auth response) is sufficient. Locally the same condition is reachable by any unprivileged user via setsockopt(TCP_USER_TIMEOUT), which has no capability check.\nUI:N - The packet storm is generated autonomously by the kernel retransmit timer once the peer advertises a zero window. No action by any local user or administrator is needed.\nS:U - The CPU, softirq and network-bandwidth exhaustion stay within the affected host\u0027s own security authority. No privilege or virtualization boundary is crossed.\nC:N - The bug only causes excessive retransmission of data already queued for and destined to that same peer \u2014 no out-of-bounds read, uninitialized memory, or kernel-pointer exposure. The only extra output is an already-existing net_dbg_ratelimited() message.\nI:N - There is no memory corruption, out-of-bounds write, or type confusion; the emitted packets are legitimate, correctly-formed retransmissions. No kernel or user data is modified.\nA:H - tcp_clamp_rto_to_user_timeout() pins the retransmit timer to 1 jiffy, producing 500\u20131000 packets/sec per socket, each with a tcp_enter_loss() and a __sk_dst_reset() route lookup, and a peer that keeps ACKing probes makes this unbounded in time rather than the 4 minutes noted in the changelog. Scaled across many connections this is a sustained, unauthenticated CPU and link-saturation denial of service, and the socket also silently ignores the TCP_USER_TIMEOUT the application relies on for failure detection."

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: fix list corruption from reorder of WRITE ->lqueued
__blkcg_rstat_flush() can be run anytime, especially when blk_cgroup_bio_start
is being executed.
If WRITE of `->lqueued` is re-ordered with READ of 'bisc->lnode.next' in
the loop of __blkcg_rstat_flush(), `next_bisc` can be assigned with one
stat instance being added in blk_cgroup_bio_start(), then the local
list in __blkcg_rstat_flush() could be corrupted.
Fix the issue by adding one barrier.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers
Check that all fields of a V2 algorithm header fit into the available
firmware data buffer.
The wmfw V2 format introduced variable-length strings in the algorithm
block header. This means the overall header length is variable, and the
position of most fields varies depending on the length of the string
fields. Each field must be checked to ensure that it does not overflow
the firmware data buffer.
As this ia bugfix patch, the fixes avoid making any significant change to
the existing code. This makes it easier to review and less likely to
introduce new bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port().
syzkaller triggered the warning [0] in udp_v4_early_demux().
In udp_v[46]_early_demux() and sk_lookup(), we do not touch the refcount
of the looked-up sk and use sock_pfree() as skb->destructor, so we check
SOCK_RCU_FREE to ensure that the sk is safe to access during the RCU grace
period.
Currently, SOCK_RCU_FREE is flagged for a bound socket after being put
into the hash table. Moreover, the SOCK_RCU_FREE check is done too early
in udp_v[46]_early_demux() and sk_lookup(), so there could be a small race
window:

|- sk = __udp4_lib_demux_lookup() |

We had the same bug in TCP and fixed it in commit 871019b22d1b ("net:
set SOCK_RCU_FREE before inserting socket into hashtable").
Let's apply the same fix for UDP.

"value": "AV:L - The racing writer side is `udp_lib_get_port()`, reached only through a local `bind()`/`connect()` syscall on a UDP socket, and the reader side needs a packet on a dst-less receive path (tun/veth), which the attacker creates locally in their own netns. A remote peer sending UDP packets cannot by itself put a socket into the unflagged window, so the bug is not remotely reachable.\nAC:L - The attacker owns both halves of the race \u2014 a thread loop calling `bind()`/`connect()` on UDP sockets and a concurrent injector feeding matching packets through tun/veth \u2014 and can widen the window by contending `hslot2-\u003elock` and by running massively in parallel across CPUs. Per the race guidance, an attacker-created race is Low complexity.\nPR:L - Binding UDP sockets requires no privilege at all, and the packet-injection side (tun/veth creation) is obtained by any unprivileged user via `unshare -Urn`, where CAP_NET_ADMIN is granted in the new user namespace. No real root or init-namespace capability is needed.\nUI:N - The attacker performs every step \u2014 socket binding, device setup, and packet injection \u2014 with no action required from any other user or administrator.\nS:U - The refcount underflow, use-after-free, and any resulting panic all occur in the kernel of the same host under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `skb_steal_sock()` reading a stale-clear `SOCK_RCU_FREE` yields `refcounted == true`, so `udp_rcv()` drops a reference it never took, freeing `struct udp_sock` while the owning fd and the hash tables still point at it. The resulting use-after-free lets an attacker refill the slab and read back kernel memory through subsequent socket operations.\nI:H - The same unbalanced `sock_put()` produces a use-after-free on a socket object containing function pointers (`sk_prot`, `sk_data_ready`, `sk_destruct`) and list heads, which is a classic heap-spray target giving arbitrary-write and control-flow-hijack primitives.\nA:H - The race trips `DEBUG_NET_WARN_ON_ONCE()` in `udp_v4_early_demux()` and the unconditional `WARN_ONCE(1, \"Found non-RCU, unreferenced socket!\")` in `sk_lookup()`, tainting the kernel and panicking outright on `panic_on_warn=1` systems; the premature socket free additionally corrupts the UDP hash lists and crashes the kernel even when not exploited further."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/shmem: disable PMD-sized page cache if needed
For shmem files, it's possible that PMD-sized page cache can't be
supported by xarray. For example, 512MB page cache on ARM64 when the base
page size is 64KB can't be supported by xarray. It leads to errors as the
following messages indicate when this sort of xarray entry is split.

Fix it by disabling PMD-sized page cache when HPAGE_PMD_ORDER is larger
than MAX_PAGECACHE_ORDER. As Matthew Wilcox pointed, the page cache in a
shmem file isn't represented by a multi-index entry and doesn't have this
limitation when the xarry entry is split until commit 6b24ca4a1a8d ("mm:
Use multi-index entries in the page cache").

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: skip to create PMD-sized page cache if needed
On ARM64, HPAGE_PMD_ORDER is 13 when the base page size is 64KB. The
PMD-sized page cache can't be supported by xarray as the following error
messages indicate.

Fix it by skipping to allocate PMD-sized page cache when its size is
larger than MAX_PAGECACHE_ORDER. For this specific case, we will fall to
regular path where the readahead window is determined by BDI's sysfs file
(read_ahead_kb).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: change vm->task_info handling
This patch changes the handling and lifecycle of vm->task_info object.
The major changes are:
- vm->task_info is a dynamically allocated ptr now, and its uasge is
reference counted.
- introducing two new helper funcs for task_info lifecycle management
- amdgpu_vm_get_task_info: reference counts up task_info before
returning this info
- amdgpu_vm_put_task_info: reference counts down task_info
- last put to task_info() frees task_info from the vm.
This patch also does logistical changes required for existing usage
of vm->task_info.
V2: Do not block all the prints when task_info not found (Felix)
V3: Fixed review comments from Felix
- Fix wrong indentation
- No debug message for -ENOMEM
- Add NULL check for task_info
- Do not duplicate the debug messages (ti vs no ti)
- Get first reference of task_info in vm_init(), put last
in vm_fini()
V4: Fixed review comments from Felix
- fix double reference increment in create_task_info
- change amdgpu_vm_get_task_info_pasid
- additional changes in amdgpu_gem.c while porting

"value": "AV:L - The vulnerability is reached through DRM ioctls on the amdgpu device node (/dev/dri/renderD128 or card0), specifically DRM_IOCTL_AMDGPU_CS job submission followed by fd close. No network or adjacent-network exposure exists.\nAC:L - The attacker controls both sides of the lifetime race: it submits a job that deterministically hangs the ring, closes the fd (which does not wait for in-flight hung jobs), and the ~10-second scheduler timeout gives a large, attacker-scheduled window to groom the freed amdgpu_fpriv slab before the coredump path dereferences the stale vm pointer.\nPR:L - An unprivileged local user with render-node access can do this \u2014 on desktop distros logind grants uaccess ACLs on /dev/dri/renderD*, and Android/ChromeOS app sandboxes and GPU-enabled containers likewise expose it. No capability check exists on the amdgpu CS ioctl path.\nUI:N - The attacking process performs every step itself \u2014 job submission, fd close, and heap grooming \u2014 with no action required from any other user.\nS:U - The stale-pointer read and its consequences stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free reads a freed kernel heap object and emits its contents into the devcoredump blob and kernel log, and the unterminated %s print can read past the field, disclosing arbitrary reallocated kernel heap data that the attacker can groom.\nI:H - Use-after-free of a slab object whose contents an attacker can control by reallocation constitutes memory corruption exploitable beyond a simple read; the unsynchronized task_info lifetime is a general object-lifetime confusion, so integrity impact is scored High per UAF guidance.\nA:H - Dereferencing the dangling vm pointer during GPU reset can oops or panic the kernel if the slab page has been returned to the page allocator, and it occurs in the non-recoverable GPU recovery path, which the attacker can trigger repeatedly."
