Synopsis

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

Description

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2027-1 advisory.

This update for the Linux Kernel 5.3.18-24_64 fixes several issues.

The following issues were fixed:

- CVE-2021-33200: Enforcing incorrect limits for pointer arithmetic operations by the BPF verifier could be abused to perform out-of-bounds reads and writes in kernel memory (bsc#1186484).
- CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values (bsc#1186111).
- CVE-2021-23134: A Use After Free vulnerability in nfc sockets allowed local attackers to elevate their privileges (bnc#1186060).
- Fixed a data loss/data corruption that occurs if there is a write error on an md/raid array (bsc#1185680).

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 kernel-livepatch-5_3_18-24_64-default package.
