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...
