      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: honor forceuid/forcegid when mapping SIDs to uid/gid\n\nWhen the administrator mounts with forceuid or forcegid (uid=/gid=\nmount options), they expect all files to appear owned by the specified\nuser/group.  However, several code paths unconditionally called\nsid_to_id() to overwrite cf_uid/cf_gid with server-provided values,\nignoring the administrator's explicit override:\n\n  - smb311_posix_info_to_fattr() (stat via POSIX extensions)\n  - cifs_posix_to_fattr() (readdir via POSIX extensions)\n  - parse_sec_desc() (CIFS ACL ownership mapping)\n\nThis allowed an untrusted server to dictate local file ownership even\nwhen the mount was configured to force specific uid/gid values.\n\nFix all three call sites to check CIFS_MOUNT_OVERR_UID and\nCIFS_MOUNT_OVERR_GID before calling sid_to_id(), following the\nsame pattern already used by cifs_unix_basic_to_fattr() for unix\nextensions.",
