Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2746-1 advisory.

 This update for the Linux Kernel 4.12.14-122_77 fixes several issues.

 The following security issues were fixed:

 - CVE-2021-22543: Fixed an issue with KVM, related to the handling of VM_IO|VM_PFNMAP vmas, which allowed users with the ability to start and control a VM to read/write random pages of memory and could result in local privilege escalation (bsc#1186482).
 - CVE-2021-37576: On the powerpc platform KVM guest OS users could cause host OS memory corruption via rtas_args.nargs (bsc#1188838).
 - CVE-2021-3609: Fixed a local privilege escalation via a race condition in net/can/bcm.c (bsc#1187215).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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.
