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.","dates":{"published":"2026-09-14T14:49:34.000Z","modified":"2026-09-15T17:00:06.103Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"clamav&distro=SUSE
