Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the netfilter component, several modules access the eth hdrskb function without properly verifying that the socket buffer skb is associated with an Ethernet device or that a valid MAC...

CVE-2026-52921

A flaw was found in the Linux kernel's netfilter ipset component. Specifically, certain hash set variants such as hash:ip,mark and hash:ip,port that iterate IPv4 ranges with a 32-bit iterator do not correctly stop at the end of the requested range. This can cause the iteration to advance beyond t...

CVE-2026-52921

CVE-2026-52921 : In the Linux kernel, netfilter ipset hash:* range iteration could continue past the upper bound when iterating IPv4 ranges, due to a 32-bit iterator not stopping at the end. This allowed traversal state to move past the requested boundary and potentially affect retries. The issue...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: dropping logically empty buckets in mtypedel The mtypedel function counts empty slots below n-pos in k, but it only drops the bucket when both n-pos and k are zero. This means that buckets whose live entries hav...

SUSE CVE-2026-45901

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: revert commitmutex usage in reset path It causes circular lock dependency between commitmutex, nfnlsubsysipset and nlkcbmutex when nft reset, ipset list, and iptables-nft with '-m set' rule run at the same...

CVE-2026-45901

A flaw was found in the Linux kernel's netfilter nftables component. This vulnerability allows a local attacker to cause a denial of service DoS by triggering a circular lock dependency. This occurs when nft reset, ipset list, and iptables-nft with a '-m set' rule are executed concurrently, leadi...
