Linux Kernel Out-of-Bounds Write Vulnerability

Linux Kernel contains an out-of-bounds write vulnerability in the ebtables SNAT target which allows an ARP sender hardware address rewrite to write directly into a nonlinear socket-buffer fragment backed by a splice-imported file page. The impacted products could be end-of-life EoL and/or...

VulnCheck KEV: CVE-2026-53266

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: socket: Lookup orig tuple for IPv6 SNAT The nfsklookupslowv4 function performs the conntrack lookup for IPv4 packets in order to restore the original 5-tuple in case of SNAT, so that the correct socket if any can be...

kernel: Linux kernel: netfilter: ebtables SNAT target writes to shared memory pages during ARP hardware address rewrite

A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...
