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-2024:3460 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: netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout (CVE-2024-26643)

* kernel: netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642)

* kernel: netfilter: nft_ct: sanitize layer 3 and 4 protocol number in custom expectations (CVE-2024-26673)

* kernel: ipv6: sr: fix possible use-after-free and null-ptr-deref (CVE-2024-26735)

* kernel: net: ip_tunnel: prevent perpetual headroom growth (CVE-2024-26804)

* kernel: cifs: fix underflow in parse_server_interfaces() (CVE-2024-26828)

* kernel: fs: sysfs: Fix reference leak in sysfs_break_active_protection() (CVE-2024-26993)

Bug Fix:

* kernel-rt: update RT source tree to the latest RHEL-9.2 ad hoc schedule build (JIRA:RHEL-36221)

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-2024:3460.
