high Nessus Plugin ID 200431

Language:

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-2024:3854 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: KVM: SVM: improper check in svm_set_x2apic_msr_interception allows direct access to host x2apic msrs (CVE-2023-5090)

* kernel: bluetooth: bt_sock_ioctl race condition leads to use-after-free in bt_sock_recvmsg (CVE-2023-51779)

* kernel: kvm: Avoid potential UAF in LPI translation cache (CVE-2024-26598)

* kernel: net/mlx5e: fix a potential double-free in fs_any_create_groups (CVE-2023-52667)

Bug Fix:

* kernel-rt: update RT source tree to the latest RHEL-9.2 ad hoc schedule build (JIRA:RHEL-38545)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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.
