CVSS 8.100000381469727 HIGH
A flaw was found in the `crypto/tls` package within the Go (golang) standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock, leading to uncontrolled consumption of resources and ultimately a denial of service (DoS).
