Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.51/6.4.14/6.5.1 and classified as critical. This issue affects an unknown part of the component wifi. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. The summary by CVE is:

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.
