CVE-2025-54331
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 issue was discovered in NPU in Samsung Mobile Processor Exynos 1380 through July 2025. There is an Untrusted Pointer Dereference of src_hdr in the copy_ncp_header function.
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 confidenceAn untrusted pointer dereference vulnerability exists in the NPU (Neural Processing Unit) of Samsung's Exynos 1380 mobile processor. The vulnerability resides in the copy_ncp_header function where the src_hdr pointer is dereferenced without proper validation, potentially allowing memory corruption or information disclosure.

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 if device uses Exynos 1380 processorCheck device specifications or system information to confirm the processor model. On Android devices, this can be found in Settings > About Phone > Model number, then research if that model uses the Exynos 1380 chipset.Affected if The device is confirmed to be powered by Samsung Exynos 1380 processor.
-
Check device firmware versionNavigate to Settings > About Phone > Software information on Samsung/Android devices, or check the kernel logs for firmware build dates. The version may appear as a date-based build (e.g., July 2025 or earlier).Affected if The firmware version date is on or before July 2025.
-
Verify NPU firmware version if accessibleOn rooted devices or through manufacturer diagnostic tools, check the NPU firmware version. This may be found in /vendor/firmware/ or similar firmware directories, or via NPU-related system logs showing the driver/firmware version.Affected if The NPU firmware version corresponds to a build dated July 2025 or earlier.
-
Confirm NPU is present and activeCheck system logs, /proc files (such as /proc/npu/version if available), or NPU-related kernel modules are loaded. The vulnerability exists in the NPU component, so the NPU must be present in the system.Affected if The device contains an NPU subsystem and the vulnerability in copy_ncp_header function is present in the loaded firmware.
A user is affected if their device contains the Exynos 1380 processor with NPU firmware dated July 2025 or earlier, where the unvalidated src_hdr pointer in the copy_ncp_header function could be exploited.
