  "title": "apparmor: validate DFA start states are in bounds in unpack_pdb",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  apparmor: validate DFA start states are in bounds in unpack_pdb  Start states are read from untrusted data and used as indexes into the DFA state tables. The aa_dfa_next() function call in unpack_pdb() will access dfa-\u003Etables[YYTD_ID_BASE][start], and if the start state exceeds the number of states in the DFA, this results in an out-of-bound read.  ==================================================================  BUG: KASAN: slab-out-of-bounds in aa_dfa_next\u002B0x2a1/0x360  Read of size 4 at addr ffff88811956fb90 by task su/1097  ...  Reject policies with out-of-bounds start states during unpacking to prevent the issue.",
