DescriptionCVE.org

In Trusted Firmware-M through 1.3.0, cleaning up the memory allocated for a multi-part cryptographic operation (in the event of a failure) can prevent the abort() operation in the associated cryptographic library from freeing internal resources, causing a memory leak.

AnalysisAI

In Trusted Firmware-M through 1.3.0, cleaning up the memory allocated for a multi-part cryptographic operation (in the event of a failure) can prevent the abort() operation in the associated. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Memory Leak (CWE-401), which allows attackers to exhaust available memory leading to denial of service. In Trusted Firmware-M through 1.3.0, cleaning up the memory allocated for a multi-part cryptographic operation (in the event of a failure) can prevent the abort() operation in the associated cryptographic library from freeing internal resources, causing a memory leak. Affected products include: Trustedfirmware Trusted Firmware-M. Version information: through 1.3.0.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Ensure all allocated memory is properly freed. Use RAII patterns or garbage-collected languages.
