Exploitation Probability (EPSS)

Low risk
0.13%

2th percentile - higher than 2% of all known CVEs

Summary

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.

Risk Assessment

This can cause out-of-bounds table access and a stack buffer overflow, potentially enabling code execution or crashing applications that process malicious PCAN frames.

Recommendation

Update software containing the PCAN parser to a patched version and validate the DLC field (<= 0x0f) before processing CAN bus data.
