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-2024:1882 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: tls: use-after-free with partial reads and async decrypt (CVE-2024-26582)

* kernel: tls: handle backlogging of crypto requests (CVE-2024-26584)

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

Bug Fix(es):

* kernel-rt: kernel: mlxsw: spectrum_acl_tcam: Fix stack corruption (JIRA:RHEL-29214)

* kernel-rt: update RT source tree to the latest RHEL-9.2 ad hoc schedule build (JIRA:RHEL-30439)

* kernel-rt: kernel: tls: use-after-free with partial reads and async decrypt (JIRA:RHEL-26399)

* kernel-rt: kernel: Marvin vulnerability side-channel leakage in the RSA decryption operation (JIRA:RHEL-29687)

* kernel-rt: kernel: tls: handle backlogging of crypto requests (JIRA:RHEL-30451)

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
