Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel's mt76 mt7921 driver related to handling of transmit status (txs) in AMSDU (Aggregated Multiple Small Data Units). If frames are aggregated in AMSDU, txs may be dropped, leading to a Small Kernel Buffer (SKB) leak within the driver. This can cause temporary network disruptions. While the issue can recover through txs timeout handling, disabling txs in AMSDU is necessary to prevent recurrence.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
