CVE-2025-54501: Improper access control on an internal debug interface could allow a high privileged attacker to bypass memory access controls potentially…
Noroxi assessment
Priority: Monitor (action score 23/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Improper access control on an internal debug interface could allow a high privileged attacker to bypass memory access controls potentially resulting in a loss of SEV-SNP guest memory integrity.
