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

Description The issue is related to sleep in atomic context bugs when uploading device dump data in mwifiex. The root cause is that dev coredumpv could not be used in atomic contexts because it calls dev set name, which includes operations that may sleep. The call tree shows execution paths that could lead to bugs, including the fw dump timer fn and mwifiex upload device dump functions. A fail log is provided, showing a call trace with a BUG message indicating a sleeping function called from an invalid context. The patch uses delayed work to replace the timer and moves operations that may sleep into a delayed work to mitigate the bugs.

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