CVE-2026-74408

A flaw was found in the Linux kernel's ath9k Wi-Fi driver. This vulnerability arises from an out-of-bounds memory access within the athtxedmatasklet function. An internal queue identifier, which is a 4-bit hardware field, can exceed the bounds of the transmit queue array. This can lead to memory...
