Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:3414 advisory.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* kernel: Marvin vulnerability side-channel leakage in the RSA decryption operation (CVE-2023-6240)

* kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function (CVE-2024-1086)

* kernel: mlxsw: spectrum_acl_tcam: Fix stack corruption (CVE-2024-26586)

* kernel: netfilter: nftables: exthdr: fix 4-byte stack OOB write (CVE-2023-52628)

* kernel: Use-after-free in nft_verdict_dump due to a race between set GC and transaction (CVE-2023-4244)

* kernel: inactive elements in nft_pipapo_walk (CVE-2023-6817)

Bug Fix(es):

* kernel-rt: update RT source tree to the latest RHEL-9.0.z Batch 17 (JIRA:RHEL-32673)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
