CVE-2026-68093

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine. When a virtual CPU vCPU is scheduled out and its physical CPU pCPU undergoes a hotplug cycle offline and then online, the vCPU might resume with an Address Space Identifier ASID that has been reassigned to another vCPU from ...

CVE-2026-68428

A flaw was found in the KVM Kernel-based Virtual Machine component of the Linux kernel. A local attacker with privileges to load and unload kernel modules could exploit a use-after-free vulnerability. This occurs when a vendor module is unloaded while the KVM module remains loaded, and a subseque...
