How to fix?

Upgrade Debian:11 mbedtls to version 2.16.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mbedtls package and not the mbedtls package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information (an RSA private key) by measuring cache usage during an import.
