The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1112 advisory.
The linux-firmware packages contain all of the firmware files that are required by various devices to operate.
Security Fix(es):
* hw: intel: Protection mechanism failure for some Intel(R) PROSet/Wireless WiFi (CVE-2022-46329)
* hw: amd: INVD instruction may lead to a loss of SEV-ES guest machine memory integrity problem (CVE-2023-20592)
Bug Fix(es):
* linux-firmware: hw: intel: Protection mechanism failure for some Intel(R) PROSet/Wireless WiFi (RHEL-14257)
* linux-firmware: hw: amd: INVD instruction may lead to a loss of SEV-ES guest machine memory integrity problem (RHEL-13978)
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 applicationโs self-reported version number.
