PostgreSQL pg_trgm heap buffer overflow writes pattern onto server memory
02 Description
PostgreSQL pg_trgm heap buffer overflow writes pattern onto server memory
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
- 0.54% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 45.4% of scored records. A rank, not a probability.
- NVD base score
- 8.2 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H
- NVD analysis status
- Modified. NVD last modified this record on 2026-07-15.
- Red Hat severity
- Important. Red Hat's rating for its own products, not a CVSS rating.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
