CVE-2026-102834 bytedeco CVE debrief

Who should care

Developers and administrators using JavaCV's IPCameraFrameGrabber, particularly those working with IP cameras and MJPEG HTTP streams, should be aware of this vulnerability and its potential impact. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. They should also plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Why it matters

This vulnerability allows for a denial-of-service attack on JavaCV's IPCameraFrameGrabber, potentially causing system instability and resource exhaustion.

• Denial of Service (DoS) via infinite loop
• Permanent hang of the frame-grabbing thread
• 100% CPU utilization by the affected thread

Technical summary

The IPCameraFrameGrabber class in JavaCV is vulnerable to an infinite-loop DoS attack due to improper bounds checking of the Content-Length value in the multipart MJPEG HTTP stream. The vulnerability occurs when a malicious or compromised camera endpoint or network attacker supplies a Content-Length value in the range 1073741825-2147483647, causing an integer overflow and infinite loop. This vulnerability can be mitigated by updating to version 1.5.14 or later, validating and sanitizing Content-Length values, and implementing bounds checking for buffer growth.

Defensive priority

High

Recommended defensive actions

• Update to version 1.5.14 or later
• Validate and sanitize Content-Length values
• Implement bounds checking for buffer growth
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The vulnerability exists in the IPCameraFrameGrabber class, specifically in the readImage() method. A malicious or compromised camera endpoint or network attacker can supply a Content-Length value in the range 1073741825-2147483647, causing an integer overflow and infinite loop. The lack of bounds checking on the Content-Length value allows for this vulnerability. Defenders should verify the affected scope, severity, and vendor guidance. The vulnerability was introduced due to the absence of proper input validation.
