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-2026-23444

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability occurs because a specific error path within the ieee80211txprepareskb function fails to properly release a network buffer, known as a socket buffer skb. This inconsistency can lead to a double-free condition, wher...
