- Summary
- ALSA: usb-audio: Prevent excessive number of frames
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Prevent excessive number of frames
In this case, the user constructed the parameters with maxpacksize 40 for rate 22050 / pps 1000, and packsize[0] 22 packsize[1] 23. The buffer size for each data URB is maxpacksize * packets, which in this example is 40 * 6 = 240; When the user performs a write operation to send audio data into the ALSA PCM playback stream, the calculated number of frames is packsize[0] * packets = 264, which exceeds the allocated URB buffer size, triggering the out-of-bounds (OOB) issue reported by syzbot [1].
Added a check for the number of single data URB frames when calculating the number of frames to prevent [1].
[1] BUG: KASAN: slab-out-of-bounds in copytourb+0x261/0x460 sound/usb/pcm.c:1487 Write of size 264 at addr ffff88804337e800 by task syz.0.17/5506 Call Trace: copytourb+0x261/0x460 sound/usb/pcm.c:1487 prepareplaybackurb+0x953/0x13d0 sound/usb/pcm.c:1611 prepareoutboundurb+0x377/0xc50 sound/usb/endpoint.c:333
