Published Jul 30, 2026 CWE-125 EPSS 0.25% (16th pctl)

Overview

CVE-2026-63550 is a medium-severity vulnerability. It was published on July 30, 2026 and has a CVSS 3.1 base score of 6.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

The MMS BER decoder contains a boundary-handling flaw in the processing

of certain fields within confirmed-request messages. When a crafted

BER-encoded element is received over an established MMS session (TCP

port 102), the decoder may advance its internal read position

incorrectly, leading to a heap out-of-bounds read. This condition causes

the MMS handling process to terminate unexpectedly, resulting in a

denial-of-service.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
