CVE-2026-31785

In the Linux kernel, the following vulnerability has been resolved: drm/xe/xe_pagefault: Disallow writes to read-only VMAs The page fault handler should reject write/atomic access to read only VMAs. Add code to handle this in xe_pagefault_service after the VMA lookup. v2: - Apply max line length (Matthew) (cherry picked from commit 714ee6754ac5fa3dc078856a196a6b124cd797a0)
