CVE-2025-9820 - Gnutls: stack-based buffer overflow in gnutls_pkcs11_token_init() function

CVE ID : CVE-2025-9820 Published : Jan. 26, 2026, 8:16 p.m. | 1 hour, 32 minutes ago Description : 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 can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.
