Type: advisorySources: OSV

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix skb leak by txs missing in AMSDU txs may be dropped if the frame is aggregated in AMSDU. When the problem shows up, some SKBs would be hold in driver to cause network stopped temporarily. Even if the problem can be recovered by txs timeout handling, mt7921 still need to disable txs in AMSDU to avoid this issue.
