CVE-2026-89516

A flaw was found in the Linux kernel's schedext component. When a Deferred Scheduling Queue DSQ is destroyed, a pending deferred re-enqueue DRU operation might still attempt to access the destroyed DSQ. This can lead to a BUGON condition, causing a kernel panic and resulting in a Denial of Servic...
