CVE-2026-22976

A flaw was found in the Linux kernel's schqfq Quick Fair Queueing scheduler. This vulnerability allows a local user to trigger a NULL pointer dereference in the qfqreset function. The issue arises when multiple qfqclass objects incorrectly reference the same leafqdisc, leading to an attempt to...
