Machine-written summary

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

This is a Linux kernel fix for the amdgpu graphics driver. The affected range is given by commits from 65781c78ad74e4260fbec92c0ecc05738044e177 onward, with fixes in several stable branches, and the kernel is affected from 4.13 with listed fixed versions such as 6.1.191, 6.6.160, 6.12.114 and 6.18.57. After a GPU reset, the KIQ ring's fence can be left unsynchronized, so a later submission may wait indefinitely; the source does not describe an attacker-controlled trigger or any impact beyond a hang. Upgrade to a kernel with the fix for your branch. No workaround is listed.
