Detailsinfo

A vulnerability was found in AMD Ryzen 9000HX Processors. It has been rated as problematic. This issue affects some unknown processing. The manipulation with an unknown input leads to a entropy in trng vulnerability. Using CWE to declare the problem leads to CWE-333. True random number generators (TRNG) generally have a limited source of entropy and therefore can fail or block. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Improper handling of insufficient entropy in the AMD CPUs could allow a local attacker to influence the values returned by the RDSEED instruction, potentially resulting in the consumption of insufficiently random values.

The advisory is shared at amd.com. The identification of this vulnerability is CVE-2025-62626 since 10/16/2025. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.
