  "title": "smb: client: honor forceuid/forcegid when mapping SIDs to uid/gid",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  smb: client: honor forceuid/forcegid when mapping SIDs to uid/gid  When the administrator mounts with forceuid or forcegid (uid=/gid= mount options), they expect all files to appear owned by the specified user/group.  However, several code paths unconditionally called sid_to_id() to overwrite cf_uid/cf_gid with server-provided values, ignoring the administrator\u0027s explicit override:    - smb311_posix_info_to_fattr() (stat via POSIX extensions)   - cifs_posix_to_fattr() (readdir via POSIX extensions)   - parse_sec_desc() (CIFS ACL ownership mapping)  This allowed an untrusted server to dictate local file ownership even when the mount was configured to force specific uid/gid values.  Fix all three call sites to check CIFS_MOUNT_OVERR_UID and CIFS_MOUNT_OVERR_GID before calling sid_to_id(), following the same pattern already used by cifs_unix_basic_to_fattr() for unix extensions.",
