What an attacker can do

A remote attacker may perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. Vendor/CNA’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality impact as high; integrity and availability impact as none. NVD’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality impact as high; integrity and availability impact as none.
