Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

This Linux kernel vulnerability affects the mt76 Wi-Fi driver for multi-link operation (MLO) stations, in kernel versions from 5.10 up to the fixes listed for each stable branch. The source gives few details on who can trigger it, but the flaw involves miscounting non-AQL packets on the wrong station link, which can cause the TX scheduler to permanently stop serving a station, a denial of service. The source does not list a workaround. Upgrade to a fixed kernel version for your branch, such as 6.1.191, 6.6.160, 6.12.110, or 6.18.52 or later.
