CVE-2018-15499 — Gearsoftware Gearaspiwdm security vulnerability

Medium CVSS 4.7

GEAR Software products that include GEARAspiWDM.sys, 2.2.5.0, allow local users to cause a denial of service (Race Condition and BSoD on Windows) by not checking that user-mode memory is available right before writing to it. A check is only performed at the beginning of a long subroutine.

Matched remediation archetype

Race condition, TOCTOU, and lifecycle synchronization

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map concurrent actors, shared state, lock boundaries, signals, callbacks, retries, and check-then-use sequences in the affected path.
  • Determine whether untrusted users can influence timing, object names, filesystem state, or repeated state transitions.
  • Identify clustered and multi-process behavior that repository-local tests may not represent.

Remediate safely

  • Make the sensitive state transition atomic or protect it with a consistently ordered synchronization primitive.
  • Perform authorization and invariant checks on the same authoritative object and transaction used for the operation.
  • Use unique private resources, safe ownership transfer, and idempotent operations; add deterministic concurrency regression tests.
