high Nessus Plugin ID 173497

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-1048 advisory.

- A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
