Name of the Vulnerable Software and Affected Versions Arm Mbed TLS versions prior to 2.24.0
Description The issue is related to the incorrect use of a revocationDate check when deciding whether to honor certificate revocation via a CRL. This can be exploited by an attacker in certain situations by changing the local clock, potentially affecting data integrity.
Recommendations For Arm Mbed TLS versions prior to 2.24.0, update to version 2.24.0 or later to resolve the issue. As a temporary workaround, consider restricting access to certificate revocation lists (CRLs) to minimize the risk of exploitation.
