02 Description
Heap buffer overflow on WireGuard receive path via unbounded incoming packet length
03 Exploitation and scoring
- Exploitation
- Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
- SSVC decision
- ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.60% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 48.6% of scored records. A rank, not a probability.
- NVD base score
- 7.4 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H
- NVD analysis status
- Analyzed. NVD last modified this record on 2026-10-24.
