Upgrade Debian:11 linux-6.1 to version 6.1.128-1~deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-6.1 package and not the linux-6.1 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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.
