The top-level symbol tables are validated this way; the nested per-class permission table is not. Reject a permission whose value exceeds nprim, which is already set when perm_read() runs. Well-formed policies are unaffected. [PM: tweak comment for line length] Join the discussion | GCVE Database | 09/04/2026, 00:00:00 UTC Added: 09/10/2026, 13:24:27 UTC |
