Executive Summary

This vulnerability involves the server verifying the TLS 1.3 PSK (Pre-Shared Key) binder using a non-constant time method. Because the verification is not done in constant time, it could potentially leak information about the PSK binder, which might be exploited by an attacker to gain knowledge about the key.

Impact Analysis

The vulnerability could allow an attacker to gain partial information about the PSK binder by measuring timing differences during verification. This could weaken the security of the TLS 1.3 connection, potentially allowing attackers to compromise the confidentiality or integrity of communications that rely on the PSK.
