In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
apparmor: check label build before no_new_privs test<\/p>\n
aa_change_profile() builds a replacement label with
\nfn_label_build_in_scope() before the no_new_privs subset check. The build
\nhelper can fail and return NULL or an ERR_PTR, but the result was passed
\nto aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL()
\ncheck.<\/p>\n
Reuse the existing target-label build failure handling immediately after
\nthe build. This preserves the current audit handling while preventing the
\nsubset helper from dereferencing an invalid label.<\/p>\n","protected":false},"excerpt":{"rendered":"
