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 in the mt7921_channel_switch_rx_beacon() or mt7925_channel_switch_rx_beacon() functions, causing a system crash. A remote attacker could potentially exploit this vulnerability to trigger a Denial of Service (DoS).
