GHSA-PW6X-273J-MP83
Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-06-25 09:31In 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.
