An attacker who can send a specially crafted packet can trigger the overflow, resulting in a temporary denial\u2011of\u2011service condition.

The issue is not listed in the CISA KEV catalog, suggesting no known widespread exploitation yet.

Mitigation requires vendor remediation and potential network filtering to reduce exposure."}}}}, "created": "2026-04-20T05:30:44.130079+00:00", "title": "Heap\u2011Based Buffer Overflow in Silex AMC Manager and SD\u2011330AC Causing Temporary Denial of Service", "updated": "2026-04-20T05:30:44.130089+00:00", "vendors": []}
