Last modified Jun 17, 2026

CVE-2021-32032 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 1.77% chance of exploitation in the next 30 days.
