Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v5.16.19

Description A potential issue exists in the kvm irq delivery to apic fast() function, which may lead to a theoretical NULL pointer dereference. The actual impact and attack plausibility have not yet been proven.

Recommendations For Linux Kernel versions prior to v5.16.19, update to version v5.16.19 or later to resolve the issue. As a temporary workaround, consider restricting access to the kvm irq delivery to apic fast() function until a patch is available.
