CVE-2026-94584: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in Brocade Fabric OS
Description
CVE-2026-94584 is a race condition vulnerability in the web management daemon of Brocade Fabric OS before version 10.0.1. It occurs during user authentication in a multi-threaded environment, causing PAM modules to process stale or incorrect client IP addresses and switch context numbers. This results in inaccurate audit records and may allow access control bypasses when AAA evaluation or Calling-Station-ID ACL policies depend on client IP attributes. The vulnerability has a low CVSS score of 2.1 and no known exploits in the wild.

Technical Analysis
This vulnerability is a thread-safety issue (CWE-362) in Brocade Fabric OS's web management daemon prior to version 10.0.1. When handling authentication requests concurrently, a race condition causes PAM modules to use incorrect client IP addresses and context numbers. This leads to inaccurate audit logs and potential bypass of access controls relying on client IP information, such as AAA policies or Calling-Station-ID ACLs.
Potential Impact
The impact includes inaccurate audit records and potential access control bypasses where authentication and authorization policies depend on client IP attributes. However, the CVSS score of 2.1 indicates the overall risk is low, and there are no reports of exploitation in the wild.
Mitigation Recommendations
No official patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should be aware of the potential for inaccurate audit records and access control issues when using affected versions.
