Doc Text:	A flaw was found in the Linux kernel's Wi-Fi driver (mt76: mt7921). This issue, caused by missing transmit status in aggregated data units, can lead to a temporary network stoppage. A local attacker could exploit this vulnerability to cause a Denial of Service (DoS) by preventing network communication.	Story Points:	---

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.
