| Classified as | CWE-415 (Double Free) |
In the Linux kernel, the following vulnerability has been resolved:
apparmor: Fix double free of ns_name in aa_replace_profiles()
if ns_name is NULL after
1071 error = aa_unpack(udata, &lh, &ns_name);
and if ent->ns_name contains an ns_name in
1089 } else if (ent->ns_name) {
then ns_name is assigned the ent->ns_name
1095 ns_name = ent->ns_name;
however ent->ns_name is freed at
