CVE-2026-109576Medium· 5.5HMS Networks PEAK-System PCAN Windows drivers Out-of-bounds Write
The parser in PEAK-System PCAN driver correctly detected the malformed record, but the loop iterating the record list advanced its processed-bytes counter even when a record had been rejected as invalid.
CVE-2026-101103Medium· 5.5HMS Networks PEAK-System PCAN Windows drivers Classic Buffer Overflow
The PEAK-System PCAN diagnostic call did not validate that the caller-supplied output buffer was large enough to hold the output record.
CVE-2026-103672High· 7.1HMS Networks PEAK-System PCAN Windows drivers Improper Validation of Array Index
The PEAK-System PCAN parser indexes a length table using attacker-controlled DLC without enforcing DLC <= 0x0f, then copies attacker payload from record+0x1c into a fixed-size stack destination.
CVE-2026-110322Medium· 5.5HMS Networks PEAK-System PCAN Windows drivers Untrusted Pointer Dereference
The PEAK-System PCAN type 0x4030 processing path fails to validate a selected/returned object pointer before dereferencing fixed fields during post-processing.
CVE-2026-105960Medium· 5.5HMS Networks PEAK-System PCAN Windows drivers Improper Handling of Length Parameter Inconsistency
PEAK-System PCAN contains a vulnerable operation involving a variable-length receive-record copy. The driver uses a requested or queued record count without sufficiently capping the copy to the actual caller-supplied output length.
