Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1955-1 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)

- The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

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

Solution

Update the affected packages.
