CVE-2024-36944
In the Linux kernel, the following vulnerability has been resolved: Reapply "drm/qxl: simplify qxl_fence_wait" This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: Reapply "drm/qxl: simplify qxl_fence_wait" This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds" and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking. Reverting the commit allows Steve's VM to boot to completion again. [ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ]
