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 ...

CVE-2026-74267 net/sched: sch_codel: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen

In the Linux kernel, the following vulnerability has been resolved: net/sched: schcodel: Do not call qdisctreereducebacklog during peek before restoring qlen Whenever codel drops packets during peek, it calls qdisctreereducebacklog.

CVE-2026-74267

The CVE concerns the Linux kernel’s traffic scheduler (net/sched sch_codel). During a peek when codel drops packets, qdisc_tree_reduce_backlog is called before the qlen is re-incremented, potentially deactivating the parent class while 1 packet remains, risking a wild memory access in certain qdi...
