CVE-2007-4315
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe AMD ATI atidsmxx.sys 3.0.502.0 driver on Windows Vista allows local users to bypass the driver signing policy, write to arbitrary kernel memory locations, and thereby gain privileges via unspecified vectors, as demonstrated by "Purple Pill".
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe AMD ATI atidsmxx.sys graphics driver version 3.0.502.0 on Windows Vista contains a vulnerability allowing local authenticated users to bypass driver signing enforcement and write to arbitrary kernel memory locations, enabling privilege escalation to kernel-level privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the atidsmxx.sys driver fileSearch for atidsmxx.sys in the Windows\System32\drivers\ directory or use 'dir /s C:\atidsmxx.sys' from an elevated command promptAffected if The file exists on the system, indicating the ATI graphics driver is installed
-
Check the driver file versionRight-click the atidsmxx.sys file, select Properties, then view the Version tab. Alternatively, use 'driverquery /v | findstr atidsmxx' from an elevated promptAffected if The file version is 3.0.502.0 or matches any version of the Amd Catalyst or Ati Catalyst driver (all versions are affected)
-
Verify if the driver is currently loadedRun 'driverquery /v | findstr atidsm' or check Device Manager under Display Adapters for an ATI/AMD graphics deviceAffected if The driver appears in the list of loaded drivers or an ATI/AMD graphics adapter is present in Device Manager
-
Confirm the Windows versionRun 'winver' or check System Properties. The CVE specifically references Windows Vista, but older Windows versions with the same driver may also be affectedAffected if The system is running Windows Vista or earlier Windows versions with the ATI Catalyst driver installed
If the atidsmxx.sys driver file exists and matches any version of the AMD or ATI Catalyst driver, the system is potentially affected by this privilege escalation vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRemove or disable the vulnerable ATI graphics driver if unnecessary; otherwise, update to a patched driver version and ensure driver signing policies are enforced. Consider application whitelisting to block unauthorized kernel drivers.
