CVE-2025-47316
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 · uneditedMemory corruption due to double free when multiple threads race to set the timestamp store.
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 double-free vulnerability exists in the timestamp store functionality where concurrent thread access can cause the same memory pointer to be freed twice, leading to heap corruption and potential arbitrary code execution.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Identify the Qualcomm firmware componentExamine system hardware specifications, device inventory, or firmware/build manifests to determine if any of the following are present: Qualcomm Aqt1000, Fastconnect 6200/6700/6800/6900/7800, Qca6391, or Qca6421 firmware modules.Affected if Any of the listed Qualcomm firmware components are present in the system, as all versions are affected.
-
Determine the firmware versionQuery the firmware version via vendor-specific tools, device APIs, or by inspecting firmware image metadata (e.g., via 'fwprintenv', 'cat /proc/version', or vendor management interfaces).Affected if The firmware version matches any of the affected product lines (all versions are vulnerable).
-
Verify timestamp store functionality is in useReview system logs, active module listings, or configuration to determine if the timestamp store feature is actively loaded or invoked by the firmware or driver stack.Affected if The timestamp store functionality is enabled or actively used on the system.
-
Check for heap corruption indicatorsAnalyze system crash dumps, kernel logs, or firmware debug logs for signs of heap corruption, double-free errors, or memory management faults related to timestamp operations.
The system is affected if it runs any version of the listed Qualcomm firmware components and the timestamp store functionality is in use, as all versions contain the double-free 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 dataImplement proper thread synchronization (e.g., mutex locks or atomic operations) around timestamp store allocation and deallocation to prevent race conditions, and validate pointer ownership before free operations.
