CVE-2023-49295 affects quic-go, an implementation of the QUIC protocol, allowing a remote attacker to induce a denial-of-service condition by exhausting the peer's memory. The attacker achieves this by sending numerous PATH_CHALLENGE frames and then manipulating the congestion window and RTT estimate to prevent the receiver from responding. Rated as Medium severity (CVSS 6.5), this vulnerability has a low attack complexity and can lead to high availability impact. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
