Summary

CVE-2023-6258 is a high-severity Improper Protection of Physical Side Channels (CWE-1300) vulnerability in Latchset Pkcs11-Provider. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Steganography (T1001.002); ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-6 (Authentication Feedback) and SI-11 (Error Handling) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

IA-6 Authentication Feedback good match

Obscures authentication feedback so that success/failure differences are not observable to attackers.

SI-11 Error Handling good match

Requires error messages to avoid revealing exploitable details, directly stopping observable response discrepancies.

PE-19 Information Leakage partial match

Directly requires protection against electromagnetic emanation leakage, which stops one class of the physical side-channel exposures described in CWE-1300.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-06 partial match

blocks

Limiting physical access reduces opportunity for side-channel observation but does not address emission-protection mechanisms inside the device.

PR.PS-06 partial match

blocks

Secure SDLC practices directly prevent observable response discrepancies via consistent error handling and timing.
