AI-suggested
A patch is available and should be applied to affected Linux kernel versions. Users should update to linux-hwe-edge kernel versions 6.5.0-1023.23~22.04.1 or later where this issue is resolved. Follow the vendor advisory at https://ubuntu.com/security/notices/USN-6895-1 for detailed update instructions.
Description
A vulnerability in the Linux kernel's nouveau driver was addressed by offloading fence uevents work to a workqueue, resolving a deadlock between the fctx lock and the irq lock. This fix prevents a denial of service condition caused by the deadlock. The issue affects multiple versions of the linux-hwe-edge kernel prior to version 6.5.0-1023.23~22.04.1 and several specific older kernel builds. The vulnerability has a medium severity rating with a CVSS score of 5.5 and does not impact confidentiality or integrity but affects availability. A patch is available and should be applied to mitigate the issue.
