{"id":"AZL-75261","summary":"CVE-2025-9820 affecting package gnutls for versions less than 3.8.3-8","details":"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.","modified":"2026-04-01T05:22:49.961664Z","published":"2026-01-26T20:16:09Z","upstream":["CVE-2025-9820"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-9820"}],"affected":[{"package":{"name":"gnutls","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gnutls"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.3-8"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-75261.json"}}],"schema_version":"1.7.5"}
