CVE-2026-23440

A flaw was found in the Linux kernel's net/mlx5e component. A race condition occurs during the handling of IPSec Internet Protocol Security Extended Sequence Number ESN updates. This can cause the system to process the same update event multiple times, leading to an incorrect ESN state. The...

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...
