Technical Summary
Red Hat issued a security advisory (RHSA-2025:19930) for the Linux kernel packages in Red Hat Enterprise Linux 9, addressing three vulnerabilities: CVE-2024-36350 (information leak via transient execution in some AMD processors), CVE-2024-36357 (transient execution vulnerability in some AMD processors), and CVE-2025-40300 (conditional IBPB mitigation for x86/vmscape). These vulnerabilities relate to transient execution side-channel issues and mitigations in the kernel. The advisory provides updated kernel packages and requires a system reboot to apply the fixes. The vulnerabilities are rated with moderate severity by Red Hat Product Security. No CVSS scores are provided in the advisory; users are referred to the CVE pages for more details.
Potential Impact
The vulnerabilities could allow information leakage and transient execution attacks on affected AMD processors and x86/vmscape subsystems, potentially exposing sensitive data. The advisory rates the impact as moderate. There are no known exploits in the wild at the time of the advisory. The issues affect the Linux kernel core component, which is critical for system operation.
Mitigation Recommendations
Red Hat has released updated kernel packages for Red Hat Enterprise Linux 9 and related variants that address these vulnerabilities. Users should apply the kernel update as described in the advisory and reboot their systems to ensure the fixes take effect. The advisory provides detailed instructions and package information at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official update and rebooting.
