In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt792x: fix use-after-free in mt76rxpollcomplete A use-after-free issue occurs in mt76rxpollcomplete due to a race condition. The STA has already been removed, but the rxstatus still had a pointer to the wcid in the...

CVE-2026-90380

CVE-2026-90380 is a use-after-free in the Linux kernel's mt76 WiFi driver (mt792x variant), occurring in mt76_rx_poll_complete due to a race condition: a station (STA) is removed but rx_status still holds a pointer to the freed wcid. The fix sets the links' wcid pointers to NULL in mt7925_sta_pre...
