Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nfc: fix races in nfc_llcp_sock_get() and nfc_llcp_sock_get_sn()
Sili Luo reported a race in nfc_llcp_sock_get(), leading to UAF.
Getting a reference on the socket found in a lookup while
holding a lock should happen before releasing the lock.
nfc_llcp_sock_get_sn() has a similar problem.
Finally nfc_llcp_recv_snl() needs to make sure the socket
found by nfc_llcp_sock_from_sn() does not disappear.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header
If an AF_PACKET socket is used to send packets through ipvlan and the
default xmit function of the AF_PACKET socket is changed from
dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option
name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and
remains as the initial value of 65535, this may trigger slab-out-of-bounds
bugs as following:
=================================================================
UG: KASAN: slab-out-of-bounds in ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan]
PU: 2 PID: 1768 Comm: raw_send Kdump: loaded Not tainted 6.0.0-rc4+ #6
ardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33

entry_SYSCALL_64_after_hwframe+0x63/0xcd
The root cause is:
1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
and skb->protocol is not specified as in packet_parse_headers()
2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()
In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.
This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nftables: exthdr: fix 4-byte stack OOB write
If priv->len is a multiple of 4, then dst[len / 4] can write past
the destination array which leads to stack corruption.
This construct is necessary to clean the remainder of the register
in case ->len is NOT a multiple of the register size, so make it
conditional just like nft_payload.c does.
The bug was added in 4.1 cycle and then copied/inherited when
tcp/sctp and ip option support was added.
Bug reported by Zero Day Initiative project (ZDI-CAN-21950,
ZDI-CAN-21951, ZDI-CAN-21961).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix out-of-bounds read when setting HMAC data.
The SRv6 layer allows defining HMAC data that can later be used to sign IPv6
Segment Routing Headers. This configuration is realised via netlink through
four attributes: SEG6_ATTR_HMACKEYID, SEG6_ATTR_SECRET, SEG6_ATTR_SECRETLEN and
SEG6_ATTR_ALGID. Because the SECRETLEN attribute is decoupled from the actual
length of the SECRET attribute, it is possible to provide invalid combinations
(e.g., secret = "", secretlen = 64). This case is not checked in the code and
with an appropriately crafted netlink message, an out-of-bounds read of up
to 64 bytes (max secret length) can occur past the skb end pointer and into
skb_shared_info:
Breakpoint 1, seg6_genl_sethmac (skb=<optimized out>, info=<optimized out>) at net/ipv6/seg6.c:208

(gdb) p/x secret
$2 = 0xffff88800b1b76c0
(gdb) p slen

The OOB data can then be read back from userspace by dumping HMAC state. This
commit fixes this by ensuring SECRETLEN cannot exceed the actual length of
SECRET.

This configuration is realised via netlink through\nfour attributes: SEG6_ATTR_HMACKEYID, SEG6_ATTR_SECRET, SEG6_ATTR_SECRETLEN and\nSEG6_ATTR_ALGID. Because the SECRETLEN attribute is decoupled from the actual\nlength of the SECRET attribute, it is possible to provide invalid combinations\n(e.g., secret = \"\", secretlen = 64). This case is not checked in the code and\nwith an appropriately crafted netlink message, an out-of-bounds read of up\nto 64 bytes (max secret length) can occur past the skb end pointer and into\nskb_shared_info:\n\nBreakpoint 1, seg6_genl_sethmac (skb=\u003coptimized out\u003e, info=\u003coptimized out\u003e) at net/ipv6/seg6.c:208\n208\t\tmemcpy(hinfo-\u003esecret, secret, slen);\n(gdb) bt\n #0 seg6_genl_sethmac (skb=\u003coptimized out\u003e, info=\u003coptimized out\u003e) at net/ipv6/seg6.c:208\n #1 0xffffffff81e012e9 in genl_family_rcv_msg_doit (skb=skb@entry=0xffff88800b1f9f00, nlh=nlh@entry=0xffff88800b1b7600,\n extack=extack@entry=0xffffc90000ba7af0, ops=ops@entry=0xffffc90000ba7a80, hdrlen=4, net=0xffffffff84237580 \u003cinit_net\u003e, family=\u003coptimized out\u003e,\n family=\u003coptimized out\u003e) at net/netlink/genetlink.c:731\n #2 0xffffffff81e01435 in genl_family_rcv_msg (extack=0xffffc90000ba7af0, nlh=0xffff88800b1b7600, skb=0xffff88800b1f9f00,\n family=0xffffffff82fef6c0 \u003cseg6_genl_family\u003e) at net/netlink/genetlink.c:775\n #3 genl_rcv_msg (skb=0xffff88800b1f9f00, nlh=0xffff88800b1b7600, extack=0xffffc90000ba7af0) at net/netlink/genetlink.c:792\n #4 0xffffffff81dfffc3 in netlink_rcv_skb (skb=skb@entry=0xffff88800b1f9f00, cb=cb@entry=0xffffffff81e01350 \u003cgenl_rcv_msg\u003e)\n at net/netlink/af_netlink.c:2501\n #5 0xffffffff81e00919 in genl_rcv (skb=0xffff88800b1f9f00) at net/netlink/genetlink.c:803\n #6 0xffffffff81dff6ae in netlink_unicast_kernel (ssk=0xffff888010eec800, skb=0xffff88800b1f9f00, sk=0xffff888004aed000)\n at net/netlink/af_netlink.c:1319\n #7 netlink_unicast (ssk=ssk@entry=0xffff888010eec800, skb=skb@entry=0xffff88800b1f9f00, portid=portid@entry=0, nonblock=\u003coptimized out\u003e)\n at net/netlink/af_netlink.c:1345\n #8 0xffffffff81dff9a4 in netlink_sendmsg (sock=\u003coptimized out\u003e, msg=0xffffc90000ba7e48, len=\u003coptimized out\u003e) at net/netlink/af_netlink.c:1921\n...\n(gdb) p/x ((struct sk_buff *)0xffff88800b1f9f00)-\u003ehead + ((struct sk_buff *)0xffff88800b1f9f00)-\u003eend\n$1 = 0xffff88800b1b76c0\n(gdb) p/x secret\n$2 = 0xffff88800b1b76c0\n(gdb) p slen\n$3 = 64 \u0027@\u0027\n\nThe OOB data can then be read back from userspace by dumping HMAC state.

CWE
- CWE-366 - Race Condition within a Thread
Summary
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.

for IPv4 packets, ovs_fragment() uses a temporary struct dst_entry. Then,
in the following call graph:
ip_do_fragment()
ip_skb_dst_mtu()
ip_dst_mtu_maybe_forward()
ip_mtu_locked()
the pointer to struct dst_entry is used as pointer to struct rtable: this
turns the access to struct members like rt_mtu_locked into an OOB read in
the stack. Fix this changing the temporary variable used for IPv4 packets
in ovs_fragment(), similarly to what is done for IPv6 few lines below.

CWE
- CWE-787 - Out-of-bounds Write
Summary
A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.
A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().
We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: fix UAF write bug in tomoyo_write_control()
Since tomoyo_write_control() updates head->write_buf when write()
of long lines is requested, we need to fetch head->write_buf after
head->io_sem is held. Otherwise, concurrent write() requests can
cause use-after-free-write and double-free problems.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

No local access to the target is needed.\nAC:L - The attacker controls both sides of the race \u2014 one side issues the sendmsg that leaves an async encryption in flight, the other issues the close that blocks in tls_encrypt_async_wait() and then frees ctx \u2014 and can retry across thousands of concurrent connections at no cost. No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading HTTPS server accepts connections from arbitrary unauthenticated clients with no client certificate in the typical deployment; locally, setsockopt(TCP_ULP,\"tls\") plus TLS_TX requires no capability at all once the tls module is loaded. Neither path needs an account or privilege on the target.\nUI:N - The race fires during ordinary kTLS record encryption and socket teardown on an established connection. No action by any local user or administrator is required.\nS:U - The use-after-free on struct tls_sw_context_tx and the resulting timer/workqueue corruption all occur in kernel memory managed by the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After kfree(ctx) the callback and the later timer expiry re-read freed, attacker-groomable memory \u2014 timer-\u003efunction, dwork-\u003ewq, and tx_work-\u003esk, the last of which is dereferenced as a struct sock * by tx_work_handler/tls_tx_records. Controlling that fake sock and the redirected call is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback performs an atomic bit-set into the reallocated slab object at a fixed offset and writes dwork-\u003ewq, dwork-\u003ecpu and timer-\u003eexpires into freed memory, then links that freed object into the global timer wheel. That yields a controlled heap write plus a function pointer read from reclaimed memory, i.e. a control-flow hijack primitive.\nA:H - Arming a delayed_work inside a freed slab object after cancel_delayed_work_sync() reliably produces slab and timer-wheel corruption, and tx_work_handler running against an already-freed TLS context oopses on the stale sk. Any of these panics the kernel."

Summary
The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

There is no remote packet-processing path into ip6_route_multipath_add().\nAC:L - The attacker creates both sides of the condition: they drop the last reference themselves and can widen the window arbitrarily by supplying many nexthops, by setting RTA_EXPIRES=0 so the non-rtnl gc softirq reaps the route, and by lowering net.ipv6.route.gc_interval inside their own netns, with unlimited retries. syzbot reproduced it, confirming reliable triggerability.\nPR:L - rtnetlink_rcv_msg() only requires netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the network namespace\u0027s user namespace, so any unprivileged local user obtains it with `unshare -Urn`. Multipath ECMP routes are addable in that namespace using RTNH_F_ONLINK gateways, which bypasses gateway reachability validation.\nUI:N - The entire sequence is performed by the attacker\u0027s own process in a single netlink transaction; no victim action, mount, or other interaction is needed.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - rt6_fill_node() reads the freed kmalloc-512 fib6_info and copies its contents into an RTM_NEWROUTE netlink message returned to the attacker\u0027s socket, including dereferencing pointers taken from freed memory such as rt-\u003efib6_metrics (passed to rtnetlink_put_metrics()), rt-\u003efib6_table, and rt-\u003efib6_nh. Reclaiming the freed slot with controlled data turns this into an arbitrary kernel-memory read leaked directly to userspace.\nI:H - This is a use-after-free on a 512-byte kmalloc object that an unprivileged attacker can spray and reclaim, after which the kernel dereferences attacker-controlled pointers and performs a list_for_each_entry_safe() walk over the freed fib6_siblings list head. That yields controlled pointer traversal and corruption suitable for privilege escalation.\nA:H - The KASAN slab-use-after-free in rt6_fill_node() causes an oops/panic when the freed object is unmapped, poisoned, or reclaimed with invalid pointers, and it can be triggered repeatedly to reliably crash the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix a memory corruption
iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.

There is no race, no memory-layout precondition, and INI debug is enabled by default, so no unusual configuration is needed.\nPR:L - Triggering requires only local access to the code path that (re)initializes the iwlwifi firmware debug configuration, with no authentication step in the path itself and no capability check inside iwl_dbg_tlv_override_trig_node. Between low and high privileges this is scored as the higher-severity Low, consistent with other locally-triggered iwlwifi memory-corruption CVEs.\nUI:N - No victim action is required \u2014 the trigger list is merged automatically at IWL_FW_INI_TIME_POINT_EARLY during normal firmware load, which occurs at boot or whenever the device is brought up.\nS:U - The overflow corrupts kernel slab memory and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The heap overflow writes past the krealloc\u0027d node into adjacent slab objects, corrupting neighbouring kernel structures such as pointers and length fields, which can be leveraged into an arbitrary kernel read primitive and disclosure of arbitrary memory.\nI:H - This is an out-of-bounds heap write of attacker-influenced content whose length (roughly 3 x data_len) and payload both come from the trigger TLV, giving a shaped write into adjacent slab objects \u2014 the standard primitive for kernel data/control-flow corruption and privilege escalation.\nA:H - Slab corruption of adjacent objects reliably produces kernel oopses, allocator BUG_ON/hardened-usercopy panics, or later crashes on freeing the smashed neighbours, resulting in a complete denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix sdma.h tx->num_descs off-by-one error
Unfortunately the commit `fd8958efe877` introduced another error
causing the `descs` array to overflow. This reults in further crashes
easily reproducible by `sendmsg` system call.

}
If an SDMA send consists of exactly 6 descriptors and requires dword
padding (in the 7th descriptor), the sdma_txreq descriptor array is not
properly expanded and the packet will overflow into the container
structure. This results in a panic when the send completion runs. The
exact panic varies depending on what elements of the container structure
get corrupted. The fix is to use the correct expression in
_pad_sdma_tx_descs() to test the need to expand the descriptor array.
With this patch the crashes are no longer reproducible and the machine is
stable.

"value": "AV:L - The overflow is driven entirely by the local sender\u0027s skb layout (number of page frags and total length), reached via an ordinary `sendmsg`/`writev` syscall on a socket routed over the hfi1 IPoIB netdev, as the reporter\u0027s `__sys_sendmsg` \u2192 `ipoib_start_xmit` \u2192 `hfi1_ipoib_send` trace shows. A remote peer cannot dictate the local skb fragment layout, so this is a local syscall vector, not network.\nAC:L - There is no race and no memory-layout dependency: the attacker deterministically chooses 4 page fragments plus a payload length not divisible by 4, which makes `num_desc` equal `desc_limit` exactly when padding is appended. Every attempt with that shape overflows `descs[6]`.\nPR:L - Any unprivileged local account can send datagrams out an IPoIB interface; no capability, no `/dev/infiniband` or `/dev/hfi1` access, and no namespace trickery is required. The `hfi1_ipoib_send` path is reached from the generic `dev_hard_start_xmit` transmit path available to all users.\nUI:N - The attacker\u0027s own `sendmsg` call triggers the overflow and the subsequent completion/reuse of the corrupted txreq; no administrator or victim action is involved.\nS:U - The out-of-bounds write stays within kernel memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The overflow clobbers `ipoib_txreq.sdma_hdr`, a pointer that is later handed to `sdma_txadd_kvaddr()`/`dma_map_single()` as the packet-header DMA source, so corrupted-pointer contents can be DMA\u0027d onto the fabric; more generally an attacker-triggered out-of-bounds write over adjacent pointer fields is memory corruption leverageable for disclosure.\nI:H - This is a straight out-of-bounds write of a 32-byte descriptor past `descs[NUM_DESC]` into the container structure, overwriting `sdma_hdr`, `priv` and `txq` (and `qp`/`wqe`/`ss` or a `list_head` in the verbs and user_sdma containers), which then serve as write targets and list-manipulation operands.\nA:H - The reporter reproduced an immediate general protection fault in `hfi1_ipoib_build_ib_tx_headers()` from the corrupted `sdma_hdr`, and the NULLed `txq`/`priv` guarantee a NULL dereference in the completion path \u2014 a repeatable kernel panic from an unprivileged syscall."
