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-2021:3360-1 advisory.

This update for the Linux Kernel 5.3.18-57 fixes several issues.

The following security issues were fixed:

- CVE-2021-31440: Fixed a lack of proper validation of user-supplied eBPF programs prior to executing them. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. (bsc#1190127).
- CVE-2021-38160: Fixed a bug that could lead to a data corruption or loss. This can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size in drivers/char/virtio_console.c (bsc#1190118)
- CVE-2021-3640: Fixed a user-after-free bug in the function sco_sock_sendmsg which could lead to local privilege escalation. (bsc#1188613)
- CVE-2021-3573: Fixed a user-after-free bug in the function hci_sock_bound_ioctl which could lead to local privilege escalation. (bsc#1187054).

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_18-57-default package.
