CVE-2026-88648

An incomplete X.509 implementation in GnuTLS v3.8.13 allows an attacker who controls a subordinate Certificate Authority to bypass cross-domain PKI restrictions . This flaw enables the unauthorized issuance of certificates. No specific remediation or exploit details are provided in the documents.

CVE-2026-88647

A hostname verification bypass exists in GnuTLS v3.8.13 , allowing a remote attacker to circumvent the Common Name fallback mechanism using a crafted certificate. This flaw can lead to information disclosure by enabling an attacker to eavesdrop on or intercept encrypted network communications. Wh...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. When validating certificates, an excessively large Subject Alternative Name SAN could cause the validation process to incorrectly revert to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in GnuTLS. The gnutlspkcs11tokensetpin function, which is used to change the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path...

Astra Linux – Vulnerability in gnutls28

A flaw in GnuTLS’ DTLS handshake parsing allows for malformed fragments with zero length and non-zero offsets. This leads to an integer underflow during reassembly, resulting in an out-of-bounds read. This issue is remotely exploitable and could cause information disclosure or denial of service...
