CVE-2025-48512
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 · uneditedIncorrect default permissions in the installation directory for the AMD general-purpose input/output controller (GPIO) could allow an attacker to achieve privilege escalation resulting in arbitrary code execution.
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 confidenceAMD GPIO software installation directory has overly permissive default file system permissions allowing unprivileged users to modify executable files or libraries. An attacker with local access can replace or modify these files to achieve privilege escalation and execute arbitrary code with elevated 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 AMD GPIO software installation directorySearch for directories named 'GPIO' or 'AMD GPIO' in common installation locations such as 'C:\Program Files\AMD', 'C:\Program Files (x86)\AMD', or use: Get-ChildItem -Path 'C:\Program Files','C:\Program Files (x86)' -Recurse -Directory -ErrorAction SilentlyContinue | Where-Object {$_.Name -like '*GPIO*' -or $_.Name -like '*amd*gpio*'}Affected if The directory exists on the system, indicating AMD GPIO software is installed.
-
Verify directory permissions for unprivileged write accessRun: Get-Acl 'path\to\AMD\GPIO\directory' | Select-Object -ExpandProperty Access | Where-Object {$_.IdentityReference -like '*Users*' -or $_.IdentityReference -like '*Everyone*' -or $_.IdentityReference -like '*Authenticated Users*'} | Select-Object IdentityReference, FileSystemRightsAffected if Any unprivileged group (Users, Everyone, Authenticated Users) has Write, Modify, or FullControl permissions to the directory.
-
Check executable file permissions in the installation directoryRun: Get-ChildItem -Path 'path\to\AMD\GPIO\directory' -Recurse -Include *.exe,*.dll,*.sys | Get-Acl | Where-Object {$_.Access | Where-Object {$_.IdentityReference -like '*Users*' -or $_.IdentityReference -like '*Everyone*'} | Where-Object {$_.FileSystemRights -match 'Write|Modify|FullControl' -and $_.AccessControlType -eq 'Allow'}}Affected if Executable files (.exe, .dll, .sys) are writable by unprivileged users.
-
Confirm write access by testing file modificationAs a standard (non-admin) user account, attempt to create or modify a test file in the AMD GPIO directory: 'Test-Path "path\to\AMD\GPIO\directory\test.txt" -Writable' or attempt echo test > 'path\to\AMD\GPIO\directory\test.txt'Affected if A standard user can successfully create or modify files in the AMD GPIO installation directory.
A system is affected if the AMD GPIO installation directory and its executables are writable by unprivileged users, allowing potential privilege escalation through file replacement.

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 dataReview and correct file system permissions on the AMD GPIO installation directory to restrict write access to privileged users only; ensure installation scripts set appropriate ownership and ACLs.
