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.
