CVE-2024-25679 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. In PQUIC before 5bde5bb, retention of unused initial encryption keys allows attackers to disrupt a connection with a PSK configuration by sending a CONNECTION_CLOSE frame that is encrypted via the initial key computed. Network traffic sniffing is needed as part of exploitation.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
