CVE-2026-80630

A flaw was found in the Linux kernel's fqcodel Fair Queueing Controlled Delay network scheduler. When fqcodel drops packets during a peek operation, it incorrectly calls qdisctreereducebacklog before restoring the queue length. This can lead to the parent's class being mistakenly deactivated,...

CVE-2026-80630

CVE-2026-80630 is a vulnerability in the Linux kernel's fq_codel traffic control qdisc (net/sched/sch_fq_codel). During the peek operation, the code calls qdisc_tree_reduce_backlog before reincrementing qlen. If qlen momentarily drops to zero while peek still returns a packet, the parent qdisc's ...
