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

A flaw was found in the GnuTLS library, specifically in the gnutlspkcs11tokeninit function that handles PKCS11 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 applicatio...
