CVE-2024-47724

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved. The issue is related to the wifi: ath11k component, where a Smatch static checker warning was triggered due to a potential sleeping in atomic context. This occurred because the ath11k bcn tx status event() function directly calls the ath11k wmi cmd send() function, which may sleep, during RCU read-side critical sections. The call trace involves several functions, including ath11k mac bcn tx event(), ath11k mac setup bcn tmpl(), and ath11k wmi bcn tmpl(). To fix this issue, a work queue is used to process beacon tx events, avoiding direct calls to ath11k mac bcn tx event() during RCU critical sections.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
