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-2026-74481 mm/page_reporting: use system_freezable_wq to fix UAF during suspend

In the Linux kernel, the following vulnerability has been resolved: mm/pagereporting: use systemfreezablewq to fix UAF during suspend During PM freeze e.g. S3 suspend or S4 hibernation, device drivers like virtioballoon reset their underlying virtio devices and delete their virtqueues via...

CVE-2026-74481

The CVE-2026-74481 entry describes a Linux kernel UAF/GPF during PM suspend caused by page_reporting work being scheduled on the non-freezable system_wq. Child devices (e.g., virtio_balloon) delete virtqueues as part of suspend, but page_reporting_process could still run, triggering virtballoon_f...

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 ...

CVE-2026-68255

A flaw was found in the kernel. A malicious virtio-gpu backend can exploit an out-of-bounds read vulnerability in the drm/virtio component of the Linux kernel. By manipulating the Extended Display Identification Data EDID block index and advertising a large size, the backend can read beyond the...

CVE-2026-68411

A flaw was found in the Linux kernel's mac80211hwsim component. A malicious backend device could report an oversized receive length to the hwsimvirtiorxwork function. This could cause the system to write past the end of a buffer, leading to a kernel panic and a denial of service DoS for the guest...
