CVE-2026-43096

A flaw was found in the Linux kernel's mshv component. A malicious guest operating system could exploit this by attempting to write to read-only memory regions or execute code in non-executable regions. This can lead to an infinite fault loop, causing the virtual CPU vCPU to spin indefinitely and...
