CVE-2025-38013 wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Set nchannels after allocating struct cfg80211scanrequest Make sure that nchannels is set after allocating the struct cfg80211registereddevice::intscanreq member. Seen with syzkaller: UBSAN:...

CVE-2025-38013

CVE-2025-38013 (Linux kernel) : Affected component is the wifi/mac80211 path. The issue is a UBSAN/array-index-out-of-bounds condition reported when setting n_channels during scan request construction, caused by allocating the scan request before the int_scan_req structure is allocated. The fix r...
