CVE-2026-80724

A flaw was found in the Linux kernel's vmclock component. This vulnerability allows a guest operating system, through a userspace process, to change a shared memory page from read-only to writable. This occurs because the vmclockmiscdevmmap function fails to properly restrict permission upgrades...

CVE-2026-80724

CVE-2026-80724 affects the Linux kernel's ptp/vmclock driver. The root cause is that vmclock_miscdev_mmap() rejects writable mappings of the shared vmclock ABI page with -EROFS but leaves VM_MAYWRITE set, allowing a guest to map the page read-only and then upgrade it to writable via mprotect(). T...
