Also fixed partial socket-write handling used for large STATS\n responses.\n * FreeBSD: Restored support for safe quarantine move and remove actions while\n preserving protection against source-path replacement races.\n * Fixed an OpenSSL library-context leak in legacy hashing helpers when a\n requested message digest cannot be fetched, such as when the default\n provider is unavailable in a FIPS-enabled environment.\n * Upgraded the Rust crossbeam-epoch dependency to resolve the\n RUSTSEC-2026-0204 advisory.\n","modified":"2026-09-16T21:45:04.898823769Z","published":"2026-09-16T08:23:41Z","related":["CVE-2025-8088","CVE-2026-20337","CVE-2026-20338","CVE-2026-20339","CVE-2026-20345","CVE-2026-20346","CVE-2026-20347","CVE-2026-20348","CVE-2026-46671"],"upstream":["CVE-2025-8088","CVE-2026-20337","CVE-2026-20338","CVE-2026-20339","CVE-2026-20345","CVE-2026-20346","CVE-2026-20347","CVE-2026-20348","CVE-2026-46671"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2026/suse-su-20264208-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1271922"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274597"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274598"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274599"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274600"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274601"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274602"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274603"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-8088"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20337"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20338"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20339"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20345"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20346"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20347"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-20348"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-46671"}],"affected":[{"package":{"name":"clamav","ecosystem":"SUSE:Linux
