CVE-2026-89803 is a high-severity vulnerability in the Linux kernel's drm/nouveau driver. It involves improper ordering in the teardown of channel-kill event subscriptions and fence contexts, which can lead to use-after-free conditions. This flaw affects Fermi and newer GPU architectures, where a kill event may access freed memory during channel destruction. The issue has been fixed by unsubscribing the channel-kill event before the fence context is torn down.
