CVE-2026-64325

A flaw was found in the Linux kernel's mt76 Wi-Fi driver, affecting mt7921 and mt7925 chipsets. When a channel-switch announcement CSA beacon is received, a timing issue can occur if a station disconnects before a queued work item processes the beacon. This can lead to a NULL pointer dereference ...
