Description OSIDB Bzimport 2025-12-24 13:04:54 UTC 
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.
