CVE-2026-74368

A flaw was found in the Linux kernel's ath12k Wi-Fi driver. When processing Wi-Fi frames, an invalid NWIFI Network Wi-Fi header length during TKIP Temporal Key Integrity Protocol MIC Message Integrity Code verification can cause an early exit from a handling function. This prevents the associated...

CVE-2026-74366

A flaw was found in the Linux kernel's ath12k Wi-Fi driver. When a new Wi-Fi link fails to initialize correctly, the driver may attempt to access uninitialized data, leading to a null pointer dereference. This can cause the system to crash, resulting in a Denial of Service DoS...
