This overflow allows the attacker to overrun memory boundaries and crash the device, resulting in a denial of service. The weakness corresponds to improper buffer bounds checks and input validation issues.", "risk_and_exploitability": "The risk is classified as a denial of service; it can be triggered by sending a specially constructed request to the vulnerable function, suggesting a network-based attack vector. No EPSS score is available and the vulnerability is not listed in the CISA KEV catalog, implying current exploitation evidence is limited. The absence of a public CVSS score makes the severity difficult to quantify, but the impact can disrupt networked services until the device is rebooted or patched."}}}}, "created": "2026-04-08T19:33:45.538680+00:00", "title": "Buffer Overflow in D-Link DI-8300 Leading to Denial of Service", "updated": "2026-04-08T19:44:43.897403+00:00", "vendors": ["dlink", "dlink$PRODUCT$di-8300"], "weaknesses": ["CWE-119", "CWE-20"]}
