Description
A flaw was found in the Linux kernel. A race condition exists in the irqchip/gic-v4 component, where a local user can force a change of affinity for a Virtual Processing Element (VPE) after it has been unmapped. This occurs because the corresponding doorbell interrupt remains visible, creating a window for exploitation. This vulnerability could lead to a denial of service.
