Summary
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.
unreferenced object 0xffff8881161d0800 (size 512):
comm "wpa_supplicant", pid 379, jiffies 4294749765
