Exploitation Probability (EPSS)

Low risk
0.10%

1th percentile - higher than 1% of all known CVEs

Summary

In the WibuKey driver for Windows below version 6.72, insufficient validation of user input when calculating the size of a kernel buffer could cause small amounts of data to be written outside the intended kernel buffer. This can lead to a system crash. Under unfavorable circumstances, adjacent kernel memory may be modified.

Risk Assessment

A local attacker could cause a system crash (DoS) or, under unfavorable conditions, modify kernel memory, potentially leading to privilege escalation.

Recommendation

Update the WibuKey driver to version 6.72 or later. Restrict access to systems with the driver installed to trusted users only.
