Description

This security bulletin contains information about 2 vulnerabilities.


1) Memory leak (CVE-ID: CVE-2026-12932)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to a memory leak in tls-crypt-v2 client key handling when processing tls-crypt-v2 client keys. A remote attacker can send a sequence of crafted inputs to cause a denial of service.

The issue can lead to an out-of-memory condition before the server crashes.


2) Input validation error (CVE-ID: CVE-2026-35058)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to improper input validation in tls_crypt_v2_extract_client_key and tls_crypt_unwrap when processing a malformed control channel packet. A remote user can send a specially crafted packet to cause a denial of service.

Only setups using tls-crypt-v2 are vulnerable. Exploitation requires possession of a valid tls-crypt-v2 client key, or observation of a handshake using a key with a specific byte property, or injection into a live client session.
