CVE-2025-62619 — Missing Authentication for Critical Function in AMD AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics

Triage

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

CISA SSVC assessment CISA

Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.

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 Device Management Portal (ADMP), AMD AMD Ryzen™ 3000 Series Desktop Processors…).
2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
4. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.

Attack characteristics

The CVSS vector, decoded. It describes the attack, not your exposure to it.

Every base score collected

Sources score independently and may disagree; each row says who scored it and under which version.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

• Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
• Review authentication logs: logins without MFA, anomalous sessions and recently created accounts.

What should defenders know first?

CVE-2025-62619 is "Missing Authentication for Critical Function in AMD AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics", rated Medium. 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 6.3 describes technical severity. EPSS 0.32% 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.
