In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: Fix memory leak after mt76 connac mcu alloc sta req()
mt76 connac mcu alloc sta req() allocates an skb which is expected to
be freed eventually by mt76 mcu skb send msg(). However, currently if
an intermediate function fails before sending, the allocated skb is
leaked.
Specifically, mt76 connac mcu sta wed update() and
mt76 connac mcu sta key tlv() may fail, leading to an immediate memory
leak in the error path.
Fix this by explicitly freeing the skb in these error paths.
Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on
mt7996 mcu sta key tlv error") made a similar change.
Compile tested only. Issue found using a prototype static analysis tool
and code review.
