| Vector | AV:L/AC:H/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s wifi subsystem, specifically within the rtw88 driver. The issue involves a potential crash and memory leak during driver unloading. This occurs because the TX purge timer and C2H queue are not properly deleted and freed when the driver is unloaded. The fix addresses this by deleting the timer and freeing the queue within the
rtw core deinit() function, and by shrinking a critical section to free the COEX queue outside of the TX report lock scope.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
