As fork() fails, we\u0027ll cleanup the maple tree, and stumble over\nthe dst VMA for which we neither performed any reservation nor copied\nany page tables.\n\nConsequently untrack_pfn() will see VM_PAT and try obtaining the\nPAT information from the page table -- which fails because the page\ntable was not copied.\n\nThe easiest fix would be to simply clear the VM_PAT flag of the dst VMA\nif track_pfn_copy() fails. However, the whole thing is about \"simply\"\nclearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy()\nand performed a reservation, but copying the page tables fails, we\u0027ll\nsimply clear the VM_PAT flag, not properly undoing the reservation ...\nwhich is also wrong.\n\nSo let\u0027s fix it properly: set the VM_PAT flag only if the reservation\nsucceeded (leaving it clear initially), and undo the reservation if\nanything goes wrong while copying the page tables: clearing the VM_PAT\nflag after undoing the reservation.\n\nNote that any copied page table entries will get zapped when the VMA will\nget removed later, after copy_page_range() succeeded; as VM_PAT is not set\nthen, we won\u0027t try cleaning VM_PAT up once more and untrack_pfn() will be\nhappy. Note that leaving these page tables in place without a reservation\nis not a problem, as we are aborting fork(); this process will never run.\n\nA reproducer can trigger this usually at the first try:\n\n  https://gitlab.com/davidhildenbrand/scratchspace/-/raw/main/reproducers/pat_fork.c\n\n  WARNING: CPU: 26 PID: 11650 at arch/x86/mm/pat/memtype.c:983 get_pat_info+0xf6/0x110\n  Modules linked in: ...\n  CPU: 26 UID: 0 PID: 11650 Comm: repro3 Not tainted 6.12.0-rc5+ #92\n  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-2.fc40 04/01/2014\n  RIP: 0010:get_pat_info+0xf6/0x110\n  ...\n  Call Trace:\n   \u003cTASK\u003e\n   ...\n   untrack_pfn+0x52/0x110\n   unmap_single_vma+0xa6/0xe0\n   unmap_vmas+0x105/0x1f0\n   exit_mmap+0xf6/0x460\n   __mmput+0x4b/0x120\n   copy_process+0x1bf6/0x2aa0\n   kernel_clone+0xab/0x440\n   __do_sys_clone+0x66/0x90\n   do_syscall_64+0x95/0x180\n\nLikely this case was missed in:\n\n  d155df53f310 (\"x86/mm/pat: clear VM_PAT if copy_p4d_range failed\")\n\n... and instead of undoing the reservation we simply cleared the VM_PAT flag.\n\nKeep the documentation of these functions in include/linux/pgtable.h,\none place is more than sufficient -- we should clean that up for the other\nfunctions like track_pfn_remap/untrack_pfn separately."

No remote peer can reach this path on its own.\nAC:L - The attacker controls both sides of the race \u2014 one thread spams DEL_ADDR/ADD_ADDR netlink commands while another creates and tears down MPTCP subflows in the same namespace, both in tight loops. Syzkaller hit it by blind fuzzing, and no special configuration is required since kernel PM and MPTCP are enabled by default.\nPR:L - MPTCP_PM_CMD_DEL_ADDR carries GENL_UNS_ADMIN_PERM, enforced as `netlink_ns_capable(skb, net-\u003euser_ns, CAP_NET_ADMIN)`, which any unprivileged user obtains via `unshare -Urn`; MPTCP socket creation and the token iterator are per-netns and need no privilege.\nUI:N - The attacker drives both the netlink command and the subflow lifecycle entirely from their own processes. No victim action is involved.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The unlocked `mptcp_for_each_subflow()` walk reads `struct mptcp_subflow_context` fields (including `tcp_sock`) from memory that a concurrent `__mptcp_close_ssk()` may have freed, and the netlink path holds no RCU read lock to defer the `kfree_rcu`. A use-after-free over a heap-groomable object gives attacker-influenced read of kernel memory.\nI:H - The stale `subflow-\u003etcp_sock` pointer is passed to `lock_sock_fast()` and `__mptcp_subflow_send_ack()`, producing writes through a freed/reallocated object; the concurrent `list_del`/`list_add_tail` against an unsynchronized traversal additionally corrupts the conn_list linkage.\nA:H - The reported symptom is a `sock_owned_by_me()` WARN, which panics outright on `panic_on_warn` systems, and following a `LIST_POISON1` pointer or a freed subflow context oopses the kernel. Any use-after-free of this kind reliably crashes the machine."

No authentication, session, or local access is needed \u2014 only the ability to get packets to a bridged endpoint.\nAC:L - Once the bridge device is in promiscuous mode (set automatically by macvlan/macvtap on top of br0, or by any tap/tcpdump \u2014 the reporter\u0027s own routine test setup), every frame crossing the bridge deterministically reaches br_pass_frame_up() and the conntrack confirm hook; the attacker wins no race and needs no special memory layout. br_netfilter + conntrack + bridging is the default configuration on Docker/Kubernetes/libvirt hosts, not a rare option.\nPR:N - The path runs in softirq context on packet receive with no capability, credential, or authentication check anywhere between the NIC and br_nf_local_in(). An unauthenticated sender is sufficient; the alternative local route via unprivileged user namespaces would only be PR:L, so None is the correct broader value.\nUI:N - Triggering requires only that the attacker transmit frames that traverse the bridge; no administrator or user on the target system needs to open, mount, or click anything.\nS:U - The faulty conntrack confirmation, the WARN, and any resulting state damage are all contained within the kernel\u0027s own network stack and its security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:N - The bug confirms conntrack entries and emits warnings; no attacker-observable memory contents or kernel addresses are returned to the attacker. The stale conntrack pointer read on the clash path feeds only a WARN_ON_ONCE and never propagates data outward.\nI:L - Attacker traffic causes the host to create and confirm conntrack entries for flows it is not a party to, and confirmation at LOCAL_IN explicitly disables NAT and conntrack helpers for those flows (per commit 62e7151ae3eb), so a bridging firewall silently fails to apply its NAT/helper policy and its connection-tracking state is polluted with attacker-seeded entries. This is a bounded, security-relevant modification of kernel firewall state rather than arbitrary write capability.\nA:H - Remotely sent frames trigger kernel WARN splats in br_nf_local_in() and __nf_conntrack_confirm(), which is a kernel panic on the many hardened/cloud/CI kernels built with panic_on_warn=1. Even without that, the failed concurrent confirms return NF_DROP (packet loss on the bridge) and a promiscuous bridge under attacker traffic fills the conntrack table with entries for observed third-party flows, exhausting nf_conntrack_max and denying service to the host\u0027s own and forwarded traffic."

Although received AX.25 frames also read dev-\u003eax25_ptr in ax25_rcv(), an adjacent radio/L2 peer cannot itself cause the free, so the attacker must be local.\nAC:L - No race needs to be won: SO_BINDTODEVICE stores ax25-\u003eax25_dev without a reference while ax25_release() drops one, so a single setsockopt+close deterministically drives the refcount to zero and kfree()s the object still published in dev-\u003eax25_ptr. The pure device-down race variant is also attacker-driven by spinning setsockopt/connect in a loop.\nPR:L - ax25_create() imposes no capability check for SOCK_DGRAM/SOCK_SEQPACKET, and the AF_AX25 module autoloads via the net-pf-3 alias, so any unprivileged local user in the init namespace can reach every vulnerable path. Root is only needed for the one-time deployment setup of the AX.25 port, not by the attacker.\nUI:N - The entire sequence is performed by the attacker\u0027s own process through socket(), setsockopt(), connect()/sendmsg() and close(); no victim action is involved.\nS:U - The freed ax25_dev and the corrupted kernel heap are entirely within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - After the free, ax25_fillin_cb() copies bytes from the reclaimed slab object into the socket\u0027s t1/t2/t3/n2/paclen/window/backoff fields, which userspace reads back with getsockopt() \u2014 a direct kernel heap disclosure \u2014 and the general UAF read of ax25_dev-\u003edev/-\u003eforward enables broader information leakage.\nI:H - The dangling pointer yields repeated refcount_dec() and stores to ax25_dev-\u003eforward and -\u003edevice_up into memory that has been reallocated for other kernel objects, giving a controlled decrement/write primitive on a groomed heap that is exploitable for privilege escalation.\nA:H - Dereferencing and freeing the already-freed ax25_dev reliably produces a kernel oops/panic (and netdev refcount underflow), and the same commit fixes a genuine sk_lock-AF_AX25 versus rtnl_mutex ABBA deadlock that permanently wedges the rtnl mutex and with it the entire networking stack."

Per kernel scoring guidance and repo precedent for BNEP/HIDP lifetime UAFs, Bluetooth reachability is Adjacent.\nAC:L - The attacker drives both halves of the lifetime race by repeatedly connecting and abruptly disconnecting, and connection teardown reliably reaches `hci_conn_del_sysfs()` with a non-rfcomm child still attached, leaving the dangling grandparent pointer every time. No condition depends on memory layout or state the attacker cannot influence.\nPR:N - The attacker is an unauthenticated adjacent Bluetooth device with no local account; the `capable(CAP_NET_ADMIN)` gate on `BNEPCONNADD` is satisfied by bluetoothd acting on the peer\u0027s behalf during normal PAN/HID service handling. This matches how the kernel CNA scored the comparable bnep/HIDP UAFs.\nUI:N - No victim action is needed \u2014 session teardown is triggered by the attacker\u0027s own disconnect, and controller unregistration occurs routinely via suspend/resume, USB dongle reset, firmware error recovery, or driver reload.\nS:U - The corrupted `hci_dev` object and the faulting code both live in the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - `device_for_each_child()` dereferences `dev-\u003ep` and walks `klist_children` inside the freed `hci_dev` slab, so an attacker who reclaims and sprays that large kmalloc allocation can steer the traversal to read arbitrary kernel memory.\nI:H - The traversal is not read-only \u2014 `klist_iter_init()` takes `spin_lock(\u0026k-\u003ek_lock)` and `kref_get()` increments refcounts through pointers taken from the freed object, yielding attacker-influenced writes and a classic UAF heap-corruption primitive suitable for control-flow hijack.\nA:H - Confirmed by the syzbot KASAN slab-use-after-free report; dereferencing the freed `hci_dev` and walking a stale klist produces a kernel oops or lockup, remotely inducible by an adjacent peer."

This mismatch causes a subsequent mprotect(PROT_WRITE) to\ntrigger a warning in page_table_check_pte_flags() due to setting the pte\nto writable while uffd-wp is still set.\n\nFix this by always explicitly clearing the uffd-wp pte/pmd flags on any\nsuch mremap() so that the values are consistent with the existing clearing\nof VM_UFFD_WP.

On the realistic deployment for this subsystem (a configured AX.25 node with a port and route), the attacker triggers it reliably every time.\nPR:L - `ax25_create()` requires no capability for SOCK_SEQPACKET/SOCK_DGRAM (only SOCK_RAW checks CAP_NET_RAW), and the autobind CAP_NET_BIND_SERVICE check is disabled by the default `ax25_uid_policy=0`, so any unprivileged local account suffices. The socket family also autoloads the module via MODULE_ALIAS_NETPROTO(PF_AX25).\nUI:N - The entire sequence is performed by the attacker\u0027s own process with no victim action required.\nS:U - The refcount underflow and resulting memory corruption stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The premature `kfree_rcu()` of `ax25_dev` leaves a freed object still reachable for reads via `dev-\u003eax25_ptr` in `ax25_rcv()`, via the `ax25_dev_list` walk, and \u2014 critically \u2014 via the world-readable `/proc/sys/net/ax25/\u003cdev\u003e/*` entries whose `.data` points into the freed slab, giving a direct read window onto whatever object is reallocated there.\nI:H - The same UAF is a write primitive: the registered sysctl table writes ints directly into the freed `ax25_dev-\u003evalues[]`, and the RX path mutates the freed object, so heap spraying yields controlled corruption of an attacker-chosen replacement object; the additional `netdev_put()` underflow can free a still-registered `net_device`.\nA:H - The unbalanced puts produce an immediate `refcount_warn_saturate()` WARN and a use-after-free that panics on the next received AX.25 frame, `bind()`, sysctl access, or DAMA timer fire; it is repeatable and also permanently corrupts the netdev refcount."

The same defect exists in the DCCP IPv6 receive path.\nAC:L - The attacker controls both sides of the race by sending a burst of concurrent SYNs from different source ports/addresses, which RSS/RPS distributes across CPUs that all enter `tcp_v6_do_rcv()` on the same listener with no socket lock held. No memory layout, timing window outside attacker influence, or victim state is required, and syzkaller reproduces it routinely.\nPR:N - The racing code runs while processing a SYN on a listening socket, entirely before connection establishment or any authentication, so no credentials of any kind are needed. Setting the `IPV6_RECV*` option that arms the path is done by the victim server (or by an unprivileged local user on their own listener), not by the attacker.\nUI:N - Triggering requires only that packets be sent to an already-listening socket; no action by any local user or administrator is needed.\nS:U - The corrupted state (`sk-\u003esk_forward_alloc`, `tcp_memory_allocated`, memcg skmem counters) and the resulting warning/panic are all within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other separate authority.\nC:N - The defect is a non-atomic read-modify-write on integer accounting counters; it produces no out-of-bounds read, no use-after-free, and no path by which memory contents or kernel pointers are disclosed to the attacker.\nI:N - No attacker-controlled data is written and no memory corruption primitive is created \u2014 only the socket\u0027s own memory-accounting counters become inconsistent, which is not a modification of protected data or control flow.\nA:H - The imbalance trips `WARN_ON_ONCE(sk_forward_alloc_get(sk))` in `inet_sock_destruct()` from softirq context, which is an immediate kernel panic on `panic_on_warn` systems, and the over-reclaim corrupts the global `tcp_memory_allocated` counter and memcg skmem accounting, breaking system-wide TCP memory limits (unbounded growth toward OOM, or permanent memory pressure across all TCP sockets). It is repeatable at will by an unauthenticated remote attacker."

              "value": "AV:L - The vulnerable code is reached only by presenting a crafted NTFS volume to the local kernel as a block device \u2014 a USB stick on an automounting kiosk/NAS/infotainment unit, or a loop/NBD-backed image mounted via udisks2 \u2014 driving mount(2) and the subsequent index walks in fs/ntfs3/index.c. No network protocol handler is involved, and physical access is not strictly required since loop and network-block-backed images work equally well.\nAC:L - Every input to the wrap \u2014 hdr-\u003ede_off, hdr-\u003eused, hdr-\u003etotal, the entry size fields, and the attribute-list layout that steers which header escapes index_hdr_check() \u2014 is an attacker-chosen byte in the image, so the corruption is deterministic with no race to win and no dependency on kernel memory layout the attacker cannot influence. The 32-bit size_t requirement is a property of the target the attacker selects, and ntfs3 automounting removable NTFS media on 32-bit ARM NAS boxes, media players, and embedded appliances is the driver\u0027s canonical deployment rather than a rare configuration.\nPR:N - The attacker needs no account or credential on the target \u2014 they only supply the malicious filesystem image, which is then mounted by root, by an automount daemon such as udisks2/systemd, or by a container/VM image-handling service acting on the attacker\u0027s data. Every privileged operation along the path is performed by the victim system on the attacker\u0027s behalf; where a local account does exist, desktop polkit loop-mount brokering provides the same reach at even lower cost.\nUI:N - On kiosks, NAS appliances, and infotainment systems that automount removable media, inserting the device triggers the mount with no human participation, and the index code runs unattended during mount itself via ntfs_security_init()\u0027s indx_init()/indx_find() on the $SDH/$SII trees rather than waiting for a subsequent file access. In the loop-device scenario the attacker performs the mount themselves, so no separate victim action is required either.\nS:U - The wrapped pointer arithmetic, out-of-bounds reads, and memmove/memcpy writes all occur in kernel heap memory within the same kernel security authority that hosts the vulnerable ntfs3 code. No VM, IOMMU, hypervisor, or sandbox boundary is crossed.\nC:H - The wrapped pointer makes hdr_first_de() return an NTFS_DE outside the index buffer, and because hdr_next_de()\u0027s bound check wraps identically with used near UINT_MAX, the entry walk proceeds past the allocation reading adjacent kernel heap as entry headers. Those bytes are consumed as file names, key_size, and MFT references and handed to userspace through ntfs_dir_emit()/dir_emit() during readdir, and steer de_get_vbn()-driven follow-on reads, making adjacent kernel memory directly observable.\nI:H - The same out-of-bounds entry pointer is passed to the mutation paths \u2014 hdr_insert_de() performs memmove(Add2Ptr(before, de_size), before, used - off) and memcpy(before, de, de_size) through it, hdr_delete_de() memmoves through it, and indx_delete_entry() applies le16_sub_cpu()/le32_sub_cpu() to fields at that address \u2014 yielding an out-of-bounds write of attacker-chosen bytes into kernel heap adjacent to the MFT-record or index-block allocation. Controlled heap overwrite of that form is a usable memory-corruption primitive for control-flow hijack, and the corrupted headers are additionally written back to disk by indx_write().\nA:H - Dereferencing and walking a pointer built from wrapped 32-bit arithmetic reads and writes past the kmalloc\u0027d index buffer, producing slab corruption and oops/panic (KASAN-class out-of-bounds), and the resulting nonsensical index geometry drives _ntfs_bad_inode()/-EINVAL error paths across the mounted volume. The fault occurs during mount or the first directory operation and can be reproduced on every mount attempt of the crafted image."

This means that\nif skb bpf_redirect_neigh() is used with a non-NULL params argument and,\nsubsequently, an XDP redirect is performed using the same\nbpf_redirect_info struct, the XDP path will get confused and end up\ncrashing, which syzbot managed to trigger.\n\nWith the stack-allocated bpf_redirect_info, the structure is no longer\nshared between the SKB and XDP paths, so the crash doesn\u0027t happen\nanymore. However, different code paths using identically-numbered flag\nvalues in the same struct field still seems like a bit of a mess, so\nthis patch cleans that up by moving the flag definitions together and\nredefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap\nwith the flags used for XDP.

This issue occurs due to improper handling of memory freeing in\nthe ishtp_hid_remove() function.\n\nThe function currently frees the `driver_data` directly within the loop\nthat destroys the HID devices, which can lead to accessing freed memory.\nSpecifically, `hid_destroy_device()` uses `driver_data` when it calls\n`hid_ishtp_set_feature()` to power off the sensor, so freeing\n`driver_data` beforehand can result in accessing invalid memory.\n\nThis patch resolves the issue by storing the `driver_data` in a temporary\nvariable before calling `hid_destroy_device()`, and then freeing the\n`driver_data` after the device is destroyed."

RapidIO is a board-level fabric interconnect, not an IP network path, so no remote or adjacent reachability exists.\nAC:L - The attacker controls both sides of the unlocked mport-\u003enet race: two concurrent RIO_DEV_ADD ioctls both allocate a net and both register a device named \"rnet_\u003cid\u003e\" under the same parent, so the loser\u0027s device_register() fails deterministically with -EEXIST, and the sequence is freely retryable. Reclaiming the freed struct rio_net (which embeds a full struct device, landing in a common kmalloc cache) via standard heap spray is routine.\nPR:L - The driver performs no capable() or permission check on any ioctl path \u2014 access is gated purely by /dev/rio_mportN node permissions, and RapidIO deployments commonly delegate fabric enumeration to non-root userspace management daemons via group-accessible device nodes. An unprivileged user with access to the mport device node can fully drive the bug.\nUI:N - Exploitation is entirely self-driven through ioctl calls by the attacker\u0027s own process; no victim action, mount, or file open by another user is needed.\nS:U - The freed object, the corruption, and the resulting privilege gain all live within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The dangling mport-\u003enet is used as a struct device parent and list head, so after slab reclamation the attacker can leak kernel pointers written back into the sprayed object and dereference attacker-influenced sysfs/kobject pointers, yielding arbitrary kernel memory disclosure.\nI:H - list_add_tail(\u0026rdev-\u003enet_list, \u0026rdev-\u003enet-\u003edevices) inserts into a freed, attacker-reclaimed list head, giving a controllable write-what-where primitive, and device_add() increments a refcount inside the freed object \u2014 both leverageable into arbitrary kernel memory write and control-flow hijack.\nA:H - Even without full exploitation, the use-after-free on mport-\u003enet and the subsequent double free via rio_free_net()/device_unregister() on freed memory reliably produce slab corruption, oops, or kernel panic."

Then it read the first\nbyte of the first 2 bytes to determine the direction.\n\nThe issue is that only the first byte indicating direction is initialized\nin current ppp driver code while the second byte is not initialized.\n\nFor normal BPF programs generated by libpcap, uninitialized data won\u0027t be\nused, so it\u0027s not a problem. However, for carefully crafted BPF programs,\nsuch as those generated by syzkaller [2], which start reading from offset\n0, the uninitialized data will be used and caught by KMSAN.\n\n[1] https://syzkaller.appspot.com/bug?extid=853242d9c9917165d791\n[2] https://syzkaller.appspot.com/text?tag=ReproC\u0026x=11994913980000"

No adjacency is required since a LANE client is an ordinary routed IP host.\nAC:L - The read-after-free is unconditional on every successful send, with no race and no memory-layout precondition: `adummy_send()` and `atmtcp_v_send()` free the skb synchronously and return 0, after which `lec_send()` always dereferences `skb-\u003elen`. Even against hardware ATM drivers that free asynchronously via `vcc-\u003epop()`, the attacker simply drives traffic to hit it repeatedly.\nPR:N - Triggering requires no credentials on the target \u2014 a remote peer merely causes a frame to be transmitted on the emulated LAN. The `capable(CAP_NET_ADMIN)` checks on `ATMLEC_CTRL`/`ATMLEC_DATA` gate only the administrative LANE setup, not the vulnerable transmit path, which is also open to any unprivileged local process via a plain `sendto()`.\nUI:N - No victim action is needed; the freed-object read happens automatically in the netdevice transmit path and in the `lec_arp_check_expire()` workqueue drain.\nS:U - The stale read and the corrupted statistics counter are entirely within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or sandbox boundary.\nC:L - The stale `skb-\u003elen` from the freed skbuff is accumulated into `dev-\u003estats.tx_bytes`, which any user can read via `/sys/class/net/lec0/statistics/tx_bytes` or `/proc/net/dev`, yielding a repeatable kernel-heap disclosure \u2014 but it is strictly bounded to 4 bytes from one fixed offset of a `SLAB_NO_MERGE` cache, so it is a limited leak rather than an arbitrary read.\nI:L - Nothing is written into the freed object, so there is no memory corruption or write primitive; the only integrity effect is that attacker-influenced garbage is folded into the interface\u0027s `tx_bytes` counter, falsifying kernel-reported accounting data.\nA:H - This is a genuine use-after-free, and on KASAN- or KFENCE-instrumented kernels the access raises a slab-use-after-free report that panics the machine outright under `panic_on_warn`, which is common in production and CI fleets."

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nudp: Fix memory accounting leak.\n\nMatt Dowling reported a weird UDP memory usage issue.\n\nUnder normal operation, the UDP memory usage reported in /proc/net/sockstat\nremains close to zero.  However, it occasionally spiked to 524,288 pages\nand never dropped.  Moreover, the value doubled when the application was\nterminated.  Finally, it caused intermittent packet drops.\n\nWe can reproduce the issue with the script below [0]:\n\n  1. /proc/net/sockstat reports 0 pages\n\n    # cat /proc/net/sockstat | grep UDP:\n    UDP: inuse 1 mem 0\n\n  2. Run the script till the report reaches 524,288\n\n    # python3 test.py \u0026 sleep 5\n    # cat /proc/net/sockstat | grep UDP:\n    UDP: inuse 3 mem 524288  \u003c-- (INT_MAX + 1) \u003e\u003e PAGE_SHIFT\n\n  3. Kill the socket and confirm the number never drops\n\n    # pkill python3 \u0026\u0026 sleep 5\n    # cat /proc/net/sockstat | grep UDP:\n    UDP: inuse 1 mem 524288\n\n  4. (necessary since v6.0) Trigger proto_memory_pcpu_drain()\n\n    # python3 test.py \u0026 sleep 1 \u0026\u0026 pkill python3\n\n  5. The number doubles\n\n    # cat /proc/net/sockstat | grep UDP:\n    UDP: inuse 1 mem 1048577\n\nThe application set INT_MAX to SO_RCVBUF, which triggered an integer\noverflow in udp_rmem_release().\n\nWhen a socket is close()d, udp_destruct_common() purges its receive\nqueue and sums up skb-\u003etruesize in the queue.  This total is calculated\nand stored in a local unsigned integer variable.\n\nThe total size is then passed to udp_rmem_release() to adjust memory\naccounting.  However, because the function takes a signed integer\nargument, the total size can wrap around, causing an overflow.\n\nThen, the released amount is calculated as follows:\n\n  1) Add size to sk-\u003esk_forward_alloc.\n  2) Round down sk-\u003esk_forward_alloc to the nearest lower multiple of\n      PAGE_SIZE and assign it to amount.\n  3) Subtract amount from sk-\u003esk_forward_alloc.\n  4) Pass amount \u003e\u003e PAGE_SHIFT to __sk_mem_reduce_allocated().\n\nWhen the issue occurred, the total in udp_destruct_common() was 2147484480\n(INT_MAX + 833), which was cast to -2147482816 in udp_rmem_release().\n\nAt 1) sk-\u003esk_forward_alloc is changed from 3264 to -2147479552, and\n2) sets -2147479552 to amount.  3) reverts the wraparound, so we don\u0027t\nsee a warning in inet_sock_destruct().  However, udp_memory_allocated\nends up doubling at 4).\n\nSince commit 3cd3399dd7a8 (\"net: implement per-cpu reserves for\nmemory_allocated\"), memory usage no longer doubles immediately after\na socket is close()d because __sk_mem_reduce_allocated() caches the\namount in udp_memory_per_cpu_fw_alloc.  However, the next time a UDP\nsocket receives a packet, the subtraction takes effect, causing UDP\nmemory usage to double.\n\nThis issue makes further memory allocation fail once the socket\u0027s\nsk-\u003esk_rmem_alloc exceeds net.ipv4.udp_rmem_min, resulting in packet\ndrops.\n\nTo prevent this issue, let\u0027s use unsigned int for the calculation and\ncall sk_forward_alloc_add() only once for the small delta.\n\nNote that first_packet_length() also potentially has the same problem.\n\n[0]:\nfrom socket import *\n\nSO_RCVBUFFORCE = 33\nINT_MAX = (2 ** 31) - 1\n\ns = socket(AF_INET, SOCK_DGRAM)\ns.bind((\u0027\u0027, 0))\ns.setsockopt(SOL_SOCKET, SO_RCVBUFFORCE, INT_MAX)\n\nc = socket(AF_INET, SOCK_DGRAM)\nc.connect(s.getsockname())\n\ndata = b\u0027a\u0027 * 100\n\nwhile True:\n    c.send(data)"

              "value": "AV:N - The bug is triggered entirely by an inbound Ethernet frame processed in the bnxt_en NAPI receive path (bnxt_rx_pkt \u2192 bnxt_xdp_build_skb), with the splat landing in ip_defrag()/skb_try_coalesce(); no local access to the target is required. Jumbo/multi-buffer frames are routable end-to-end inside jumbo-enabled datacenter and cloud VPC fabrics, so the sender need not share the victim\u0027s L2 segment.\nAC:L - On an affected host (Broadcom NetXtreme NIC, jumbo MTU, multi-buffer XDP program returning XDP_PASS) every oversized packet deterministically produces the wrong truesize \u2014 the upstream reproducer is a single `ping -s 65000`. There is no race to win and no memory-layout condition outside the attacker\u0027s control.\nPR:N - The vulnerable code executes in softirq/NAPI context on raw received frames, long before any socket lookup, authentication, or capability check. An unauthenticated attacker with no account on the target simply emits packets.\nUI:N - No victim action is needed at attack time; the XDP program and jumbo MTU are pre-existing deployment configuration, not interaction solicited from a user. Packet arrival alone drives the entire path.\nS:U - The miscounted truesize corrupts skb and socket memory accounting within the same kernel security authority that owns the RX path. No VM, container, or IOMMU boundary is crossed.\nC:N - Only the truesize accounting field is wrong; skb-\u003efrags[] and xdp_frags_size retain their correct values, so no out-of-bounds or uninitialized memory is read or exposed to userspace. Nothing is disclosed to the attacker.\nI:N - There is no out-of-bounds write, type confusion, or control-flow corruption \u2014 the erroneous value only skews internal memory-accounting counters, whose consequence is availability rather than data modification.\nA:H - The under-counted truesize trips WARN_ON_ONCE(delta \u003c len) in skb_try_coalesce() during IP reassembly, which is an immediate kernel panic on the panic_on_warn configurations common in cloud and hardened fleets. Even without panic_on_warn, sk_rmem_alloc/sk_forward_alloc and the IP-defrag memory limit are under-charged by roughly the frag count, letting a remote flood pin several times the configured buffer memory and drive the system to OOM."
