Astra Linux – Vulnerability in Linux, Linux 5.10
In the net/netfilter/nftablesapi.c file within the Linux kernel, up to version 5.18.1, it is possible for a local user who can create user/net namespaces to escalate privileges to root. This occurs because an incorrect NFTSTATEFULEXPR check leads to a use-after-free vulnerability...
Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: netfilter: nfttproxy: restrict to prerouting hook TPROXY is only allowed during prerouting, but nfttproxy does not check this. This fix resolves a crash null dereference that occurs when using tproxy from, for example, the output...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15
A use-after-free vulnerability was discovered in the Linux kernel’s netfilter subsystem, specifically in the net/netfilter/nftablesapi.c file. Improper error handling related to NFTMSGNEWRULE allows a dangling pointer to be used within the same transaction, leading to a use-after-free...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: clonesetfence only applies to the flushed set Syzbot, using fault injection, triggered a failing memory allocation with GFPKERNEL, resulting in a WARN message: iter.err WARNING: net/netfilter/nftablesapi.c:84...
Unity Linux 20.1050e Security Update: kernel (UTSA-2026-021636)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-021636 advisory. In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsocket: fix sk refcount leaks We must put 'sk' reference before returning. Tenable...
CVE-2026-43916 pam_authnft: Heap buffer overflow in NETLINK_SOCK_DIAG reply walker
pamauthnft is a PAM session module binding nftables firewall rules to authenticated sessions via cgroupv2 inodes. Prior to 0.2.0-alpha, a heap buffer over-read in peerlookuptcp src/peerlookup.c:134, prior to the fix allowed a crafted NETLINKSOCKDIAG reply to slip past the message-size check, then...
PT-2026-46007
Name of the Vulnerable Software and Affected Versions Linux kernel versions 6.2 and later Description A desynchronization issue exists in the nft inner parse l2l3 function when processing inner IPv6 packets. While the ipv6 find hdr function correctly calculates the transport header offset by...
CVE-2026-43453
A flaw was found in the Linux kernel's netfilter component, specifically within the nftsetpipapo module. The pipapodrop function performs a stack out-of-bounds read. This occurs when an argument is evaluated at the call site before the function body executes, leading to a read beyond the allocate...
UBUNTU-CVE-2026-43453
In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetpipapo: fix stack out-of-bounds read in pipapodrop pipapodrop passes rulemapi + 1.n to pipapounmap as the tooffset argument on every iteration, including the last one where i == m-fieldcount - 1. This reads one...
PT-2026-39114
Name of the Vulnerable Software and Affected Versions Linux kernel versions 5.10 through 6.19 Description A stack out-of-bounds read exists in the nftables pipapo set backend within the pipapo drop function. The issue occurs because the function passes rulemapi + 1.n to pipapo unmap as the to...
CVE-2026-43114
A flaw was found in the Linux kernel's netfilter component, specifically within the nftsetpipapoavx2 AVX2 matching functions. This vulnerability occurs when a pipapo set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as...
CVE-2026-43114
In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetpipapoavx2: don't return non-matching entry on expiry New test case fails unexpectedly when avx2 matching functions are used. The test first loads a ranomly generated pipapo set with 'ipv4 . port' key, i.e. nft -...
