kernel: Linux kernel rt2x00 Wi-Fi driver: Denial of Service via memory leak during device removal

A flaw was found in the Linux kernel's rt2x00 Wi-Fi driver. A local user could exploit this vulnerability when a rt2x00 device is removed, as its associated channel surveys are not properly freed. This leads to a memory leak, which could result in a Denial of Service DoS due to resource exhaustio...

kernel: wifi: ath12k: Handle lock during peer_id find

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Handle lock during peerid find ath12kpeerfindbyid requires that the caller hold the ab-baselock. Currently the WBM error path does not hold the lock and calling that function, leads to the following lockdepassertin...

kernel: wifi: mt76: do not run mt76u_status_worker if the device is not running

A flaw was discovered in the Linux kernel’s mt76 Wi-Fi driver, where the mt76ustatusworker thread could be scheduled even when the underlying device was not yet in a running state. Under certain conditions, this could lead to a NULL pointer dereference in the worker routine, resulting in a kernel...
