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-2021:3073-1 advisory.

 This update for the Linux Kernel 4.12.14-122_37 fixes several issues.

 The following security issues were fixed:

 - CVE-2021-3653: Fixed missing validation of the KVM `int_ctl` VMCB field that would have allowed a malicious L1 guest to enable AVIC support for the L2 guest (bsc#1189420).
 - CVE-2021-3656: Fixed KVM nSVM nested VMLOAD/VMSAVE interception (bsc#1189418).
 - CVE-2021-38198: Fixed KVM MMU to use the correct inherited permissions to get shadow page (bsc#1189278).

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.
