CVE-2025-0011 is a vulnerability identified in AMD Ryzen™ 8000 Series Desktop Processors related to improper removal of sensitive information before storage or transfer within the AMD Crash Defender feature. Specifically, this vulnerability falls under CWE-212, which concerns the improper removal of sensitive data from memory or storage before it is reused or transferred. In this case, the flaw allows an attacker with limited privileges (local access with low privileges) to potentially obtain kernel address information. Kernel address information is critical for system security as it can be used to bypass kernel-level protections such as Kernel Address Space Layout Randomization (KASLR). The vulnerability does not require user interaction and has a low complexity for exploitation, but it is limited to local attackers with some privileges. The CVSS v3.1 base score is 3.3, indicating a low severity primarily due to the limited impact (loss of confidentiality only) and the requirement for local privileges. There is no indication that the vulnerability affects integrity or availability, nor that it can be exploited remotely. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability could be leveraged as part of a multi-stage attack to escalate privileges or evade security mechanisms by revealing kernel memory layout details.

For European organizations, the impact of CVE-2025-0011 is primarily a potential confidentiality breach of kernel address information on systems running AMD Ryzen™ 8000 Series Desktop Processors. While the direct impact is limited, the exposure of kernel addresses can facilitate more advanced attacks such as privilege escalation or bypassing security mitigations. Organizations with sensitive workloads or those relying on AMD Ryzen 8000 series in desktop environments (e.g., developer workstations, administrative consoles) could see increased risk if attackers gain local access. However, since exploitation requires local privileges and does not affect server-grade processors directly, the threat is somewhat contained. Still, in environments where endpoint security is critical, such as financial institutions, government agencies, or critical infrastructure operators in Europe, this vulnerability could be a stepping stone for attackers to gain deeper system access. The lack of known exploits reduces immediate risk, but the presence of this vulnerability necessitates vigilance and proactive mitigation.

1. Apply patches and firmware updates from AMD as soon as they become available to address the improper data removal in Crash Defender. 2. Restrict local access to systems running AMD Ryzen 8000 Series processors by enforcing strict access controls and endpoint security policies. 3. Employ robust privilege management to minimize the number of users with local privileges that could exploit this vulnerability. 4. Use security monitoring tools to detect unusual local activity that might indicate attempts to exploit kernel information leaks. 5. Consider enabling additional kernel protection mechanisms such as Kernel Page Table Isolation (KPTI) and enhanced KASLR implementations where possible. 6. Conduct regular security audits and vulnerability assessments on endpoints to ensure no unauthorized local access is possible. 7. Educate users and administrators about the risks of local privilege misuse and the importance of maintaining updated systems.
