02 Description
OpenVM byte decomposition of pc in AUIPC chip can overflow
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.47% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 40.7% of scored records. A rank, not a probability.
- NVD base score
- 7.8 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector
