CVE-2026-31415

The Linux Kernel, the operating system core itself.

Security Fix(es):

IEEE P802.11-REVme D1.1 through D7.0 allows FragAttacks against mesh networks. In mesh networks using Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP), an adversary can exploit this vulnerability to inject arbitrary frames towards devices that support receiving non-SSP A-MSDU frames. NOTE: this issue exists because of an incorrect fix for CVE-2020-24588. P802.11-REVme, as of early 2025, is a planned release of the 802.11 standard.(CVE-2025-27558)

In the Linux kernel, the following vulnerability has been resolved:

net/sched: act_ife: Fix metalist update behavior

Whenever an ife action replace changes the metalist, instead of replacing the old data on the metalist, the current ife code is appending the new metadata. Aside from being innapropriate behavior, this may lead to an unbounded addition of metadata to the metalist which might cause an out of bounds error when running the encode op:

To solve this issue, fix the replace behavior by adding the metalist to the ife rcu data structure.(CVE-2026-23378)

In the Linux kernel, the following vulnerability has been resolved:

icmp: fix NULL pointer dereference in icmp_tag_validation()

icmp_tag_validation() unconditionally dereferences the result of rcu_dereference(inet_protos[proto]) without checking for NULL. The inet_protos[] array is sparse -- only about 15 of 256 protocol numbers have registered handlers. When ip_no_pmtu_disc is set to 3 (hardened PMTU mode) and the kernel receives an ICMP Fragmentation Needed error with a quoted inner IP header containing an unregistered protocol number, the NULL dereference causes a kernel panic in softirq context.

net: usb: cdc_ncm: add ndpoffset to NDP32 nframes bounds check

The same bounds-check bug fixed for NDP16 in the previous patch also exists in cdc_ncm_rx_verify_ndp32(). The DPE array size is validated against the total skb length without accounting for ndpoffset, allowing out-of-bounds reads when the NDP32 is placed near the end of the NTB.

Add ndpoffset to the nframes bounds check and use struct_size_t() to express the NDP-plus-DPE-array size more clearly.

In the Linux kernel, a security vulnerability exists in the IOMMU Shared Virtual Addressing (SVA) feature. On x86 architecture when CONFIG_X86 is set, IOMMU hardware caches kernel page table entries. Due to the lack of notification mechanism for kernel page table changes, when kernel page table pages are freed and reused, the IOMMU may retain stale entries, leading to Use-After-Free (UAF) and Write-After-Free (WAF) conditions. This can be exploited to cause arbitrary physical memory DMA access or privilege escalation.(CVE-2025-71089)

In the Linux kernel, the following vulnerability has been resolved:

uacce: fix cdev handling in the cleanup path

When cdev_device_add fails, it internally releases the cdev memory, and if cdev_device_del is then executed, it will cause a hang error. To fix it, we check the return value of cdev_device_add() and clear uacce->cdev to avoid calling cdev_device_del in the uacce_remove.(CVE-2026-23096)

In the Linux kernel, the following vulnerability has been resolved: ipv6: avoid overflows in ip6_datagram_send_ctl() Yiming Qian reported : <quote> I believe I found a locally triggerable kernel bug in the IPv6 sendmsg ancillary-data path that can panic the kernel via skb_under_panic() (local DoS). The core issue is a mismatch between: - a 16-bit length accumulator (struct ipv6_txoptions::opt_flen, type __u16) and - a pointer to the last provided destination-options header (opt->dst1opt) when multiple IPV6_DSTOPTS control messages (cmsgs) are provided. - include/net/ipv6.h: - struct ipv6_txoptions::opt_flen is __u16 (wrap possible). (lines 291-307, especially 298) - net/ipv6/datagram.c:ip6_datagram_send_ctl(): - Accepts repeated IPV6_DSTOPTS and accumulates into opt_flen without rejecting duplicates. (lines 909-933) - net/ipv6/ip6_output.c:__ip6_append_data(): - Uses opt->opt_flen + opt->opt_nflen to compute header sizes/headroom decisions. (lines 1448-1466, especially 1463-1465) - net/ipv6/ip6_output.c:__ip6_make_skb(): - Calls ipv6_push_frag_opts() if opt->opt_flen is non-zero. (lines 1930-1934) - net/ipv6/exthdrs.c:ipv6_push_frag_opts() / ipv6_push_exthdr(): - Push size comes from ipv6_optlen(opt->dst1opt) (based on the pointed-to header). (lines 1179-1185 and 1206-1211) 1. opt_flen is a 16-bit accumulator: - include/net/ipv6.h:298 defines __u16 opt_flen; /* after fragment hdr */. 2. ip6_datagram_send_ctl() accepts repeated IPV6_DSTOPTS cmsgs and increments opt_flen each time: - In net/ipv6/datagram.c:909-933, for IPV6_DSTOPTS: - It computes len = ((hdr->hdrlen + 1) << 3); - It checks CAP_NET_RAW using ns_capable(net->user_ns, CAP_NET_RAW). (line 922) - Then it does: - opt->opt_flen += len; (line 927) - opt->dst1opt = hdr; (line 928) There is no duplicate rejection here (unlike the legacy IPV6_2292DSTOPTS path which rejects duplicates at net/ipv6/datagram.c:901-904). If enough large IPV6_DSTOPTS cmsgs are provided, opt_flen wraps while dst1opt still points to a large (2048-byte) destination-options header. In the attached PoC (poc.c): - 32 cmsgs with hdrlen=255 => len = (255+1)*8 = 2048 - 1 cmsg with hdrlen=0 => len = 8 - Total increment: 32*2048 + 8 = 65544, so (__u16)opt_flen == 8 - The last cmsg is 2048 bytes, so dst1opt points to a 2048-byte header. 3. The transmit path sizes headers using the wrapped opt_flen: - In net/ipv6/ip6_output.c:1463-1465: - headersize = sizeof(struct ipv6hdr) + (opt ? opt->opt_flen + opt->opt_nflen : 0) + ...; With wrapped opt_flen, headersize/headroom decisions underestimate what will be pushed later. 4. When building the final skb, the actual push length comes from dst1opt and is not limited by wrapped opt_flen: - In net/ipv6/ip6_output.c:1930-1934: - if (opt->opt_flen) proto = ipv6_push_frag_opts(skb, opt, proto); - In net/ipv6/exthdrs.c:1206-1211, ipv6_push_frag_opts() pushes dst1opt via ipv6_push_exthdr(). - In net/ipv6/exthdrs.c:1179-1184, ipv6_push_exthdr() does: - skb_push(skb, ipv6_optlen(opt)); - memcpy(h, opt, ipv6_optlen(opt)); With insufficient headroom, skb_push() underflows and triggers skb_under_panic() -> BUG(): - net/core/skbuff.c:2669-2675 (skb_push() calls skb_under_panic()) - net/core/skbuff.c:207-214 (skb_panic() ends in BUG()) - The IPV6_DSTOPTS cmsg path requires CAP_NET_RAW in the target netns user namespace (ns_capable(net->user_ns, CAP_NET_RAW)). - Root (or any task with CAP_NET_RAW) can trigger this without user namespaces. - An unprivileged uid=1000 user can trigger this if unprivileged user namespaces are enabled and it can create a userns+netns to obtain namespaced CAP_NET_RAW (the attached PoC does this). - Local denial of service: kernel BUG/panic (system crash). - ---truncated---

In the Linux kernel, the following vulnerability has been resolved:

ipv6: avoid overflows in ip6_datagram_send_ctl()

Yiming Qian reported : <quote> I believe I found a locally triggerable kernel bug in the IPv6 sendmsg ancillary-data path that can panic the kernel via skb_under_panic() (local DoS).

The core issue is a mismatch between:

• a 16-bit length accumulator (struct ipv6_txoptions::opt_flen, type __u16) and
• a pointer to the last provided destination-options header (opt->dst1opt)

when multiple IPV6_DSTOPTS control messages (cmsgs) are provided.

• include/net/ipv6.h:
  • struct ipv6_txoptions::opt_flen is __u16 (wrap possible). (lines 291-307, especially 298)
• net/ipv6/datagram.c:ip6_datagram_send_ctl():
  • Accepts repeated IPV6_DSTOPTS and accumulates into opt_flen without rejecting duplicates. (lines 909-933)
• net/ipv6/ip6_output.c:__ip6_append_data():
  • Uses opt->opt_flen + opt->opt_nflen to compute header sizes/headroom decisions. (lines 1448-1466, especially 1463-1465)
• net/ipv6/ip6_output.c:__ip6_make_skb():
  • Calls ipv6_push_frag_opts() if opt->opt_flen is non-zero. (lines 1930-1934)
• net/ipv6/exthdrs.c:ipv6_push_frag_opts() / ipv6_push_exthdr():
  • Push size comes from ipv6_optlen(opt->dst1opt) (based on the pointed-to header). (lines 1179-1185 and 1206-1211)

1. opt_flen is a 16-bit accumulator:

• include/net/ipv6.h:298 defines __u16 opt_flen; /* after fragment hdr */.

2. ip6_datagram_send_ctl() accepts repeated IPV6_DSTOPTS cmsgs and increments opt_flen each time:

• In net/ipv6/datagram.c:909-933, for IPV6_DSTOPTS:
  • It computes len = ((hdr->hdrlen + 1) << 3);
  • It checks CAP_NET_RAW using ns_capable(net->user_ns, CAP_NET_RAW). (line 922)
  • Then it does:
    • opt->opt_flen += len; (line 927)
    • opt->dst1opt = hdr; (line 928)

There is no duplicate rejection here (unlike the legacy IPV6_2292DSTOPTS path which rejects duplicates at net/ipv6/datagram.c:901-904).

If enough large IPV6_DSTOPTS cmsgs are provided, opt_flen wraps while dst1opt still points to a large (2048-byte) destination-options header.

In the attached PoC (poc.c):

• 32 cmsgs with hdrlen=255 => len = (255+1)*8 = 2048
• 1 cmsg with hdrlen=0 => len = 8
• Total increment: 32*2048 + 8 = 65544, so (__u16)opt_flen == 8
• The last cmsg is 2048 bytes, so dst1opt points to a 2048-byte header.

3. The transmit path sizes headers using the wrapped opt_flen:

• In net/ipv6/ip6_output.c:1463-1465:
  • headersize = sizeof(struct ipv6hdr) + (opt ? opt->opt_flen + opt->opt_nflen : 0) + ...;

With wrapped opt_flen, headersize/headroom decisions underestimate what will be pushed later.

4. When building the final skb, the actual push length comes from dst1opt and is not limited by wrapped opt_flen:

• In net/ipv6/ip6_output.c:1930-1934:
  • if (opt->opt_flen) proto = ipv6_push_frag_opts(skb, opt, proto);
• In net/ipv6/exthdrs.c:1206-1211, ipv6_push_frag_opts() pushes dst1opt via ipv6_push_exthdr().
• In net/ipv6/exthdrs.c:1179-1184, ipv6_push_exthdr() does:
  • skb_push(skb, ipv6_optlen(opt));
  • memcpy(h, opt, ipv6_optlen(opt));

With insufficient headroom, skb_push() underflows and triggers skb_under_panic() -> BUG():

• net/core/skbuff.c:2669-2675 (skb_push() calls skb_under_panic())

• net/core/skbuff.c:207-214 (skb_panic() ends in BUG())

• The IPV6_DSTOPTS cmsg path requires CAP_NET_RAW in the target netns user namespace (ns_capable(net->user_ns, CAP_NET_RAW)).

• Root (or any task with CAP_NET_RAW) can trigger this without user namespaces.

• An unprivileged uid=1000 user can trigger this if unprivileged user namespaces are enabled and it can create a userns+netns to obtain namespaced CAP_NET_RAW (the attached PoC does this).

• Local denial of service: kernel BUG/panic (system crash).

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. (CVE-2025-54505)

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. (CVE-2025-54518)

It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could possibly use this issue to influence the values returned by the RDSEED instruction causing loss of confidentiality and integrity. (CVE-2025-62626)

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose sensitive information (kernel memory). (CVE-2023-45896)

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. (CVE-2025-54505)

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. (CVE-2025-54518)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:
