In the Linux kernel, the following vulnerability has been resolved: apparmor: validate DFA start states are in bounds in unpackpdb Start states are read from untrusted data and used as indexes into the DFA state tables. The aadfanext() function call in unpackpdb() will access dfa->tables[YYTDIDBASE][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 aadfanext+0x2a1/0x360 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.
