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.
