CVE-2026-87683

8.6 high SSVC exploitation: none Analyzed

Multiple stack-based buffer overflow vulnerabilities exist in the REST API management component of Brocade Fabric OS versions prior to 10.0.1. When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.
