FWIW, there's also second commit mentioned in the bugzilla, http://git.kernel.org/cgit/linux/kernel/git/jberg/mac80211.git/commit/?id=1d147bfa64293b2723c4fec50922168658e613ba that also fixes a crash. It is questionable how the attacker can trigger these bugs differently than normal (high load) usage on a smp box. -- Petr Matousek / Red Hat Security Response Team PGP: 0xC44977CA 8107 AF16 A416 F9AF 18F3 D874 3E78 6F42 C449 77CA
