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-2024:2846 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: untrusted VMM can trigger int80 syscall handling (CVE-2024-25744)

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

Bug Fix(es):

* kernel-rt: kernel: untrusted VMM can trigger int80 syscall handling (JIRA:RHEL-30421)

* kernel-rt: kernel: netfilter: nftables: exthdr: fix 4-byte stack OOB write (JIRA:RHEL-31093)

* kernel-rt: update RT source tree to the latest RHEL-9.2 ad hoc schedule build (JIRA:RHEL-34746)

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.

Solution

Update the RHEL kernel-rt package based on the guidance in RHSA-2024:2846.
