|---|---|---|---|---|---|---|---|
| CVE-2025-14831 | Med | 5.3 | < 3.8.10-3.el10_1 | 3.8.10-3.el10_1 | Feb 9, 2026 | A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central Processing Unit) and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names (SANs). | |
| CVE-2025-9820 | Med | 4.0 | < 3.8.10-3.el10_1 | 3.8.10-3.el10_1 | Jan 26, 2026 | A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error c | |
| CVE-2025-6395 | Med | 6.5 | < 3.8.9-9.el10_0.14 | 3.8.9-9.el10_0.14 | Jul 10, 2025 | A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). | |

When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory | |
| CVE-2025-32989 | Med | 5.3 | < 3.8.9-9.el10_0.14 | 3.8.9-9.el10_0.14 | Jul 10, 2025 | A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extensi | |
| CVE-2025-32988 | Med | 6.5 | < 3.8.9-9.el10_0.14 | 3.8.9-9.el10_0.14 | Jul 10, 2025 | A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() | |
| CVE-2024-12243 | Med | 5.3 | < 3.6.16-8.el8_10.3 | 3.6.16-8.el8_10.3 | Feb 10, 2025 | A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to sen | |
| CVE-2024-28834 | Med | 5.3 | < 3.6.16-8.el8_9.3 | 3.6.16-8.el8_9.3 | Mar 21, 2024 | A flaw was found in GnuTLS.

| CVE-2022-2509 | — | < 3.7.6-12.el9_0 | 3.7.6-12.el9_0 | Aug 1, 2022 | A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. | ||
| CVE-2021-3580 | — | < 3.6.16-4.el8 | 3.6.16-4.el8 | Aug 5, 2021 | A flaw was found in the way nettle's RSA decryption functions handled specially crafted ciphertext. An attacker could use this flaw to provide a manipulated ciphertext leading to application crash and denial of service. | ||
| CVE-2021-20232 | — | < 3.6.16-4.el8 | 3.6.16-4.el8 | Mar 12, 2021 | A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. | ||
