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-2022:3123-1 advisory.

This update for the Linux Kernel 5.14.21-150400_24_16 fixes several issues.

The following security issues were fixed:
- CVE-2020-36516: Fixed an off-path attack via mixed IPID assignment method with the hash-based IPID assignment policy to inject data into a victim's TCP session or terminate that session (bsc#1196867).
- CVE-2021-39698: Fixed possible memory corruption in aio_poll_complete_work of aio.c, that could have led to local escalation of privilege with no additional execution privileges needed (bsc#1196959).
- CVE-2022-36946: Fixed a remote denial of service attack inside nfqnl_mangle in net/netfilter/nfnetlink_queue.c, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative length (bsc#1201941).

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_14_21-150400_24_18-default package.
