CVE-2026-102834: JavaCV: Integer Overflow in IPCameraFrameGrabber Causes Infinite-Loop DoS

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-16 · updated 2026-10-28
• Weakness: CWE-190

Description

JavaCV provides Java interfaces to OpenCV, FFmpeg, and other multimedia libraries. Prior to 1.5.14, IPCameraFrameGrabber doubles a 32-bit buffer capacity without checking for overflow or bounding the parsed Content-Length. An application consumes an MJPEG response from a malicious camera endpoint or a tampered plaintext stream. The source can return an oversized Content-Length header in an MJPEG stream. Successful exploitation can trap the frame-grabbing thread in a permanent CPU-spinning loop and deny service. This issue is fixed in version 1.5.14.
