McPvDrv.sys 4.6.111.0 in McAfee File Lock 5.x in McAfee Total Protection allows local users to obtain sensitive information from kernel memory or cause a denial of service (system crash) via a large VERIFY_INFORMATION.Length value in an IOCTL_DISK_VERIFY ioctl call.

Analyst readout for executives and security teams

Plain-English summary

This is a local flaw in a McAfee File Lock driver bundled with McAfee Total Protection 5.x. A user already on the machine could make the driver expose sensitive kernel memory or crash Windows. It is not described as remotely exploitable in the supplied sources.

Executive priority

Treat this as a moderate legacy endpoint risk. It requires local access, but the impact reaches kernel memory disclosure or full system crash. Prioritize inventory and removal from managed systems, especially where shared workstations, kiosks, or lower-trust users exist.

Technical view

McPvDrv.sys 4.6.111.0 mishandles a large VERIFY_INFORMATION.Length value submitted through an IOCTL_DISK_VERIFY request. The reported impact is kernel memory disclosure or denial of service by system crash. The affected scope in the sources is McAfee File Lock 5.x in McAfee Total Protection.

Likely exposure

Exposure is likely limited to Windows endpoints running McAfee Total Protection with McAfee File Lock 5.x and McPvDrv.sys version 4.6.111.0. The source bundle does not identify broader McAfee products, server products, or fixed versions.

Exploitation context

The supplied CVE data and references describe local-user exploitation potential, not remote attack. CISA KEV status is false in the bundle, and no cited source states active exploitation. Public disclosure occurred in January 2016, so details have been public for years.

Researcher notes

Evidence is limited to the CVE description and two public references. The bundle does not provide CVSS, CWE, patch information, exploit-in-the-wild evidence, or complete affected CPE data. Avoid expanding scope beyond McAfee File Lock 5.x and McPvDrv.sys 4.6.111.0.

Mitigation direction

  • Inventory endpoints for McAfee File Lock 5.x and McPvDrv.sys 4.6.111.0.
  • Check McAfee guidance for fixed versions, workarounds, or product retirement direction.
  • Remove or disable the File Lock component where business-approved and vendor-supported.
  • Limit unnecessary local user access on systems that still carry the vulnerable driver.
  • Prioritize replacement of unsupported legacy consumer security software.

Validation and detection

  • Confirm whether McAfee File Lock is installed on managed Windows endpoints.
  • Record McPvDrv.sys version where the component exists.
  • Review endpoint crash telemetry for unexplained driver-related system crashes.
  • Verify vendor support status for each detected McAfee Total Protection installation.
  • Document any systems awaiting vendor guidance or component removal.
