CVE-2026-61390

Status: DeferredHigh (7.7)—

There is a heap buffer overflow vulnerability in some Hikvision cameras, which may allow unauthenticated attackers to cause device malfunction by sending specially crafted packets.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H
Base score: 7.7

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.38%
Percentile among all scored CVEs: 29
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
