Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: seq: oss: Fix races at processing SysEx messages<br /> <br /> OSS sequencer handles the SysEx messages split in 6 bytes packets, and<br /> ALSA sequencer OSS layer tries to combine those. It stores the data<br /> in the internal buffer and this access is racy as of now, which may<br /> lead to the out-of-bounds access.<br /> <br /> As a temporary band-aid fix, introduce a mutex for serializing the<br /> process of the SysEx message packets.
