In the Linux kernel, the following vulnerability has been resolved:
wifi: fix leak if split 6 GHz scanning fails
rdev->int scan req is leaked if cfg80211 scan() fails. Note that it's
supposed to be released at cfg80211 scan done() but this doesn't happen
as rdev->scan req is NULL at that point, too, leading to the early return
from the freeing function.
