Description

ALSA: seq: oss: Fix races at processing SysEx messages

In the Linux kernel, the following vulnerability has been resolved:

ALSA: seq: oss: Fix races at processing SysEx messages

OSS sequencer handles the SysEx messages split in 6 bytes packets, and

ALSA sequencer OSS layer tries to combine those. It stores the data

in the internal buffer and this access is racy as of now, which may

lead to the out-of-bounds access.

As a temporary band-aid fix, introduce a mutex for serializing the

process of the SysEx message packets.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
