CVE-2026-74568

CVE-2026-74568 (Linux kernel, KVM arm64 vgic) : A race between LPIs release and re-registration can occur when an LPI’s reference count drops to zero and the LPI entry is evicted from the VGIC LPI xarray, enabling a concurrent re-registration to overwrite or leak LPIs. The issue arises because th...
