CVE-2024-26598

CVE-2024-26598 is a Linux kernel vulnerability affecting KVM on arm64 with vgic-its. The issue is a use-after-free risk in the LPI translation cache: vgic_its_check_cache() drops a lock that serializes refcount changes without first elevating the vgic_irq refcount. If a translation cache hit race...
