Linux Kernel ath11k Monitor Mode Data Handling Vulnerability

A vulnerability in the Linux kernel's ath11k wireless driver has been addressed. The issue arose because the ath11k_hal_srng_* functions, used in monitor mode, did not properly lock shared ring data, leading to potential data handling warnings. This vulnerability was particularly evident in full monitor mode, where the lack of synchronization could cause issues during data processing. The vulnerability has been resolved by adding the necessary locks to protect the shared data, ensuring proper synchronization during monitor mode operations.

Impact

The vulnerability could lead to data processing warnings and potential mismanagement of shared data in monitor mode, which could disrupt normal wireless operations.
