| * | ALSA: usb-audio: Fix copy&paste error in the validator | Takashi Iwai | 2019-10-22 | 1 | -1/+1 |
| | | | | | | | | | | | | | The recently introduced USB-audio descriptor validator had a stupid copy&paste error that may lead to an unexpected overlook of too short descriptors for processing and extension units. It's likely the cause of the report triggered by syzkaller fuzzer. Let's fix it. Fixes: 57f8770620e9 ("ALSA: usb-audio: More validations of descriptor units") Reported-by: syzbot+0620f79a1978b1133fd7@syzkaller.appspotmail.com Link: https://lore.kernel.org/r/s5hsgnkdbsl.wl-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de> | ||||
| * | ALSA: usb-audio: More validations of descriptor units | Takashi Iwai | 2019-08-22 | 1 | -0/+332 |
| Introduce a new helper to validate each audio descriptor unit before and check the unit before actually accessing it. This should harden against the OOB access cases with malformed descriptors that have been recently frequently reported by fuzzers. The existing descriptor checks are still kept although they become superfluous after this patch. They'll be cleaned up eventually later. Signed-off-by: Takashi Iwai <tiwai@suse.de> | |||||
