medium Nessus Plugin ID 198060

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:3462 advisory.

 The kernel packages contain the Linux kernel, the core of any Linux operating system.

 Security Fix(es):

 * RHEL: Add Spectre-BHB mitigation for AmpereOne (CVE-2023-3006)

 * kernel: net:emac/emac-mac: Fix a use after free in emac_mac_tx_buf_send (CVE-2021-47013)

 * kernel: net: bridge: data races indata-races in br_handle_frame_finish() (CVE-2023-52578)

 Bug Fix(es):

 * XFS: thaw operation hungs if caches are dropped while FS is frozen (JIRA:RHEL-34522)

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 package based on the guidance in RHSA-2024:3462.
