Linux Kernel Vulnerability in ath11k Driver Affecting WLAN Hardware

CVE-2025-39732

What is CVE-2025-39732?

A vulnerability in the ath11k driver of the Linux kernel arises from the use of a non-atomic function, ath11k_mac_disable_peer_fixed_rate, within an atomic context. This can lead to unexpected behavior, specifically a warning indicating that a sleeping function was called from an invalid context. Proper adjustments are necessary to ensure that operations that may sleep are not executed in an atomic context, which can affect WLAN performance and stability.
