CVE-2024-50192 is a vulnerability in the Linux kernel's irqchip/gic-v4 component where a race condition allows userspace to attempt a VMOVP operation on a dying Virtual Processing Element (VPE). This occurs because the VPE can be unmapped while its doorbell interrupt remains visible, potentially causing instability. The issue is addressed by checking the vmapp_count to ensure the VPE is still mapped before allowing changes.
