CVE-2026-74311

A flaw was found in the Linux kernel. During a system restore operation, the virtio real-time clock RTC component fails to properly manage virtual queues virtqueues. If the reinitialization of these virtqueues fails, the system attempts to delete queues using incorrect memory references. This can...

CVE-2026-74311

CVE-2026-74311 affects the Linux kernel virtio rtc path. The bug occurs when viortc_restore() calls viortc_init_vqs() without removing old virtqueues, enabling vp_del_vqs() to reference a NULL info pointer in vp_del_vq() and crash the guest kernel during restore. The fix deletes stale virtqueues ...
