Linuxsecurity AMD Microcode Vulnerabilities Expose Sensitive Data Risks
Article Content
- •AMD processors are vulnerable to data leakage and entropy issues.
- •Local attackers can exploit these vulnerabilities to access sensitive information.
- •Patches are available, and users must reboot their systems after updates.
Recent discoveries by researchers Oleksii Oleksenko and colleagues revealed vulnerabilities in AMD processors that could allow local attackers to infer sensitive data and exploit insufficient entropy in the RDSEED instruction. Specifically, CVE-2024-36350 and CVE-2024-36357 relate to data leakage risks, while CVE-2025-62626 addresses issues with random value generation. These vulnerabilities affect AMD Zen 5 processors, posing risks to confidentiality and integrity. Users are advised to update their systems to mitigate these risks. The vulnerabilities were disclosed on June 25, 2026, and patches are available for affected systems. Users must reboot their systems after updates to ensure changes take effect.
