CVE-2025-52539
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 · uneditedA buffer overflow with Xilinx Run Time Environment may allow a local attacker to read or corrupt data from the advanced extensible interface (AXI), potentially resulting in loss of confidentiality, integrity, and/or availability.
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 buffer overflow vulnerability exists in the Xilinx Run Time Environment that allows a local attacker to overflow a buffer and interact with the Advanced eXtensible Interface (AXI), potentially reading or corrupting data in memory. This could lead to loss of confidentiality, integrity, and availability of the affected system.

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.
-
Check if Xilinx Run Time Environment is installedSearch for Xilinx RTE installation directories or executables on the system. Common locations include /opt/Xilinx, C:\Xilinx, or check installed programs/package manager listings.Affected if Xilinx RTE software is found on the system and no patch has been applied.
-
Determine the installed Xilinx RTE versionLocate the Xilinx RTE version information. This may be in version files, About dialogs within Xilinx tools, or version flags on RTE executables. Compare the found version against any Xilinx security advisories for CVE-2025-52539.Affected if A version of Xilinx RTE is installed that matches the affected versions listed in Xilinx security advisories for this CVE.
-
Verify AXI interface access is availableInspect whether AXI-related modules, drivers, or interfaces are loaded or accessible in the Xilinx RTE environment. Check for AXI bus bridges, memory-mapped AXI registers, or AXI DMA configurations.Affected if AXI interfaces or AXI-related components are enabled or accessible within the RTE environment, providing a pathway for the buffer overflow to interact with AXI.
-
Assess local user access to the systemReview local user accounts and permissions on the system running Xilinx RTE. Check for unprivileged or shared local accounts that could exploit the local attack vector.Affected if Multiple local users exist or untrusted local accounts have access to the system running Xilinx RTE, enabling the local attacker vector.
A user is affected if Xilinx RTE is installed with a vulnerable version and AXI interfaces are accessible to a local attacker on the system.

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 vendor-supplied patches for the Xilinx Run Time Environment when available; until then, restrict local access to systems running the affected RTE and monitor for unauthorized AXI access attempts.
