CVE-2026-99167

A flaw was found in the Linux kernel's traffic control net/sched subsystem. Due to improper synchronization in the tcfactionput function, reference and binding counts are updated out of sequence during action cleanup, allowing memory to be released while still being accessed. A local attacker cou...
