CVE-2026-72347

A flaw was found in the Linux kernel's netfilter xtconnmark module. This vulnerability occurs because the CONNMARK target, specifically revision 2, accepts user-controlled shift parameters without proper validation. An attacker with the ability to create netfilter rules could provide a shiftbits...
