"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: reject an unclaimed class value in security_get_classes()\n\nsecurity_get_classes() sizes an array by p_classes.nprim and fills it at\nvalue - 1, so a class value the policy never defines leaves a NULL.\nsel_make_classes() passes every entry to sel_make_dir(), reaching the same\nd_alloc_name() dereference as the permission array. The class symbol table\nis allowed to be sparse (policydb_class_isvalid() exists to absorb that),\nbut this getter builds its own array straight from the hash table and has\nno such predicate.\n\nFail the lookup when a value went unclaimed instead of handing out the\nNULL. Conforming policies define every class they declare and are\nunaffected."
