CVE-2026-64298

CVE-2026-64298: Linux kernel NFSv4: when O_TRUNC is used, the open permission mask must include MAY_WRITE so the local check aligns with server behavior. Current nfs_open_permission_mask() derives the mask from O_ACCMODE, which can let an open(O_RDONLY|O_TRUNC) pass local checks while the server ...
