HMS Networks PEAK-System PCAN Windows drivers Classic Buffer Overflow

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The PEAK-System PCAN diagnostic call did not validate that the caller-supplied output buffer was large enough to hold the output record.
