CVE-2026-22024 is a medium-severity vulnerability affecting NASA's CryptoLib. This vulnerability allows a memory leak through the cryptography_encrypt() function, which allocates multiple buffers for HTTP requests and JSON parsing that are never freed. As a result, each call leaks approximately 400 bytes of memory. Sustained traffic can gradually exhaust available memory, leading to performance degradation or service disruption. Organizations should prioritize patching immediately.
The vulnerability has a CVSS score of 6.3, indicating a medium severity level. Its classification as a medium severity vulnerability means that while it is not critical, it poses a significant risk that can lead to resource exhaustion if left unaddressed. The vulnerability was published on January 10, 2026, and has been patched in version 1.4.3.
Risk to organizations includes potential service disruptions due to memory exhaustion, particularly for applications relying on sustained traffic. It is crucial for defenders to assess their exposure to this vulnerability and take action to mitigate risks.
The urgency for organizations is high, as the vulnerability has been analyzed and a patch is available. Immediate action is necessary to ensure systems are not left vulnerable to this exploit.
Vulnerability Details
According to the official CVE description, this vulnerability affects the CryptoLib software, which provides a software-only solution using the CCSDS Space Data Link Security Protocol for secure communication between spacecraft and ground stations. Prior to version 1.4.3, the cryptography_encrypt() function has a memory leak issue that can lead to resource exhaustion.
The vulnerability is classified under CWE-401, which pertains to memory leaks. The CVSS score of 6.3 indicates a medium severity level, and it has been analyzed and confirmed. Organizations should note that the affected versions are all prior to 1.4.3.
Technical Analysis
The root cause of this vulnerability stems from the cryptography_encrypt() function's allocation of multiple buffers without freeing them, resulting in a memory leak. The attack vector is network-based, and the complexity is low, meaning that no special conditions are required to exploit the vulnerability. Importantly, no privileges are required to exploit this issue, and user interaction is not necessary.
The impact of this vulnerability primarily affects availability due to the gradual exhaustion of memory resources. While there is no impact on confidentiality or integrity, the issue can lead to significant service disruptions if exploited.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a risk as sustained traffic could exploit the memory leak, leading to denial of service. Organizations should consider the potential blast radius, as affected systems may experience gradual degradation in performance, ultimately resulting in outages.
Given the CVSS score of 6.3, organizations should address this vulnerability in their priority patch cycle. The associated risk of service disruption necessitates prompt attention.
