The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:7429 advisory.
This is a kernel live patch module which can be loaded by the kpatch command line utility to modify the code of a running kernel. This patch module is targeted for kernel-4.18.0-553.16.1.el8_10.
Security Fix(es):
* kernel: virtio-net: tap: mlx5_core short frame denial of service (CVE-2024-41090)
* kernel: virtio-net: tun: mlx5_core short frame denial of service (CVE-2024-41091)
* kernel: wifi: mac80211: Avoid address calculations via out of bounds array indexing (CVE-2024-41071)
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.
