CVE-2026-92152: CWE-129: Improper Validation of Array Index in nasa fprime
Description
CVE-2026-92152 is a critical vulnerability in NASA's F Prime (fprime) framework versions 4.1.0 up to but not including 4.2.0. The issue involves improper validation of an array index in the Svc::GenericHub output-port dispatch, where a deserialized port field is used without explicit range checks. This can lead to out-of-bounds array access, causing heap corruption and potentially enabling remote code execution. The vulnerability is fixed in version 4.2.0.

Technical Analysis
The vulnerability in NASA's F Prime framework (versions >=4.1.0 <4.2.0) arises from improper validation of the output-port array index in the Svc::GenericHub component. Specifically, the deserialized port field is passed to output port handlers (serialOut_out, bufferOut_out, eventOut_out, tlmOut_out) without checking if the index is within the valid range. In builds with assertions enabled, this causes an abort on out-of-bounds access. In builds without assertions, it can lead to heap memory corruption and potentially remote code execution. The issue is resolved in version 4.2.0.
Potential Impact
Exploitation of this vulnerability can cause heap corruption and may allow an unauthenticated remote attacker to execute arbitrary code on the affected system. Systems running vulnerable versions of the F Prime framework without assertion checks are at risk of memory corruption and remote compromise. Assertion-enabled builds will abort, causing denial of service. The CVSS 4.0 score is 9.3 (critical), reflecting the high impact and ease of exploitation without privileges or user interaction.
Mitigation Recommendations
Upgrade to F Prime version 4.2.0 or later, where this vulnerability is fixed. No other mitigations are specified. Patch status is confirmed as fixed in 4.2.0.
