CVE-2026-43096

In the Linux kernel mshv component, CVE-2026-43096 patches an infinite fault loop caused by permission-denied GPA intercepts. The issue occurred when guest access to memory regions triggered remaps for all faults on movable regions, even if access type wasn’t permitted, causing a re-fault and vCP...

CVE-2013-1943

The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted...
