FAQ

How could an attacker exploit this vulnerability? An unauthenticated attacker could exploit the vulnerability by sending specially crafted network traffic to the TLS server and could cause it to crash. According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L)? What does that mean for this vulnerability? An attacker who successfully exploited this vulnerability might be able to disclose a single byte of kernel memory. While this is technically information disclosure, the loss is very low.
