kernel: irqchip/gic-v4: Don't allow a VMOVP on a dying VPE

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...

The vulnerability of the irqchip/gic-v4 components of the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the irqchip/gic-v4 components in the Linux operating system’s kernel is related to resource management errors. Exploiting this vulnerability can allow an attacker to cause service failures...
