CVE-2026-23449

A flaw was found in the Linux kernel's Traffic Equalizer TEQL network scheduler. When a TEQL device uses a lockless Queueing Discipline Qdisc as its root, a race condition can occur during the qdiscreset operation if it is not properly synchronized with the datapath. This can lead to a double-fre...

CVE-2026-23449

Summary (CVE-2026-23449) : The Linux kernel vulnerability is in the TEQL scheduler path (net/sched/teql) where a lockless Qdisc root can cause a double-free in skb_release_data via an unsafe qdisc_reset path. The underlying issue occurs when teql_master_xmit fails to use seq_lock to guard qdisc_r...

CVE-2026-23340

CVE-2026-23340 affects the Linux kernel net sched subsystem where qdisc_reset_all_tx_gt() can race with the lockless dequeue path, potentially causing use-after-free of skbs when the number of real TX queues changes (e.g., via ethtool -L on virtio-net). The fix is to serialize qdisc_reset() again...
