Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2042-1 advisory.

This update for the Linux Kernel 4.4.180-94_141 fixes several issues.

The following issues were fixed:

- CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values (bsc#1186111).
- CVE-2021-32399: Fixed a race condition when removing the HCI controller (bnc#1184611).
- Fixed a regression with the last livepatch which caused a kernel warning during sysfs read (bsc#1186235).

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 kgraft-patch-4_4_180-94_141-default package.
