Weaknesses
CWE-193, CWE-476

Description

TLS 1.3 embeds the actual record type as the last non-zero byte of the decrypted payload, optionally followed by zero padding. The code which searches for the inner record type had an off-by-one bug which could be triggered by an invalid frame, leading to an underflow followed by an unconditional NULL pointer dereference, causing a kernel panic. A remote TLS 1.3 peer can send a specially crafted record to trigger a kernel panic, resulting in a Denial of Service (DoS).

Affected configurations

• freebsd freebsd 14.4 • freebsd freebsd 14.5 • freebsd freebsd 15.0 • freebsd freebsd 15.1
