Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak occurs during split 6 GHz scanning when the
cfg80211 scan() function fails. The rdev->int scan req variable is leaked because the cleanup process in cfg80211 scan done() is bypassed when rdev->scan req is also NULL, causing the function to return early without freeing the allocated memory.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
