CVE-2025-48520
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 · uneditedAn improper input validation vulnerability within the AMD Platform Management Framework (PMF) driver can allow a local attacker to read Out-of-Bounds potentially resulting in information disclosure or a crash
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 confidenceA local attacker can exploit improper input validation in the AMD Platform Management Framework (PMF) driver to read memory outside allocated buffers. This out-of-bounds read vulnerability may expose sensitive system information or cause the system to crash.

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.
-
Verify AMD PMF driver presenceCheck if the AMD Platform Management Framework driver is installed. On Windows, run 'driverquery /v | findstr -i pmf' or check Device Manager for 'AMD PMF' under System devices. On Linux, run 'lsmod | grep -i amd_pmf' or check 'modinfo amd_pmf' to confirm the kernel module is loaded.Affected if AMD PMF driver or kernel module is present on the system
-
Retrieve installed driver versionObtain the exact version of the installed AMD PMF driver. On Windows, run 'sc query AMDPmfService' or check driver properties in Device Manager. On Linux, run 'modinfo amd_pmf' and note the version string from the output.Affected if Driver version cannot be determined or is older than the vendor-patched version
-
Confirm PMF service statusVerify whether the AMD PMF service is active. On Windows, run 'sc query AMDPmfService' to check service state. On Linux, check if the amd_pmf module is currently loaded into the kernel via 'lsmod | grep amd_pmf'.Affected if PMF service is running and driver version is unpatched
-
Inspect kernel/driver logs for memory access eventsReview system logs for out-of-bounds read indicators. On Windows, open Event Viewer and filter for Event ID 0 or check 'dmesg' for 'amd_pmf' messages. On Linux, run 'dmesg | grep -i pmf' or check '/var/log/syslog' for PMF-related error messages about memory access violations.Affected if Logs show memory access violations, buffer overflow errors, or unexpected behavior related to AMD PMF driver
System is affected if AMD PMF driver is installed with a version prior to the patched release and the driver/service is active, enabling a local attacker to trigger the out-of-bounds read 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 dataApply the AMD-provided firmware/driver update for the PMF component to address the input validation flaw. Verify that all affected AMD systems receive the patch in a timely manner.
