CVE-2026-68166
A flaw was found in the Linux kernel's userfaultfd mechanism. A local attacker with userfaultfd access could register on shadow stack Virtual Memory Areas VMAs. By discarding a page and injecting a page with chosen return addresses, an attacker could achieve arbitrary code execution. This...

CVE-2026-68166
The CVE-2026-68166 issue in the Linux kernel is addressed by restricting userfaultfd registrations. The fix updates vma_can_userfault() to reject VM_SHADOW_STACK and VM_SPECIAL so that drivers implementing vm_uffd_ops cannot register special VMAs with userfaultfd. VM_SPECIAL’s inclusion of VM_DON...
