CVE-2025-29951 — Stack-based Buffer Overflow in AMD AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics

A buffer overflow in the AMD Secure Processor (ASP) bootloader could allow an attacker to overwrite memory, potentially resulting in privilege escalation and arbitrary code execution.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+1
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (AMD AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics, AMD AMD Ryzen™ Embedded R1000 Series Processors, AMD AMD Ryzen™ Embedded R2000 Series Processors…).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (memory corruption), errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.

What should defenders know first?

CVE-2025-29951 is "Stack-based Buffer Overflow in AMD AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics", rated High. It affects AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics (AMD); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.3 describes technical severity. EPSS 0.15% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
