CVE-2026-45873 netfilter: nft_set_rbtree: check for partial overlaps in anonymous sets

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetrbtree: check for partial overlaps in anonymous sets Userspace provides an optimized representation in case intervals are adjacent, where the end element is omitted. The existing partial overlap detection logic...

CVE-2026-45873

The CVE concerns the Linux kernel netfilter component nft_set_rbtree. It fixes an issue where the partial overlap detection logic incorrectly skipped overlap checks for start elements in anonymous sets that use an optimized adjacent-interval representation (end element omitted). Specifically, two...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the local overlap detection logic in netfilter’s nftsetrbtree. This logic skips the initial eleme...

Linux Distros Unpatched Vulnerability : CVE-2026-45873

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetrbtree: skip end interval element from gc Lazy garbage collection for rbtree during insertions may collect end interval elements that have just been added during these transactions. These elements are skipped, as...

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. This vulnerability, located in the nftsetpipapoavx2 functionality, is caused by incorrect data processing during AVX2 matching operations. This can lead to the system incorrectly identifying or matching network data entries within...

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 -...
