"value": "In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: fix NULL sock in aa_sock_file_perm\n\nDeal with the potential that sock and sock-sk can be NULL during\nsocket setup or teardown. This could lead to an oops. The fix for NULL\npointer dereference in __unix_needs_revalidation shows this is at\nleast possible for af_unix sockets. While the fix for af_unix sockets\napplies for newer mediation this is still the fall back path for older\naf_unix mediation and other sockets, so ensure it is covered."
