Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2023-5981
CWEhttps://cwe.mitre.org/data/definitions/208.html

A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.

Weakness

Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not.
