CVE-2023-42567
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 · uneditedImproper size check vulnerability in softsimd prior to SMR Dec-2023 Release 1 allows stack-based buffer overflow.
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 size validation flaw in softsimd allows a caller to provide data that exceeds expected buffer boundaries, causing a stack-based buffer overflow. This could enable an attacker to overwrite stack frames and potentially achieve 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.
-
Verify Android version is 14.0Check the device Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Android version is exactly 14.0 on a Samsung device
-
Confirm softsimd component is presentCheck if the softsimd library or service exists on the system (common paths include /system/lib/softsimd or as a system service)Affected if softsimd is present and loaded on the device
-
Determine softsimd versionQuery the softsimd version through available system interfaces, logs, or library metadata if accessibleAffected if softsimd version is earlier than the SMR Dec-2023 Release 1 update
A Samsung Android 14.0 device with softsimd present and running a version earlier than SMR Dec-2023 Release 1 is affected by this buffer overflow vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpdate softsimd to the SMR Dec-2023 Release 1 or later, which includes proper size validation before buffer operations.
SMR Dec-2023 Release 1 (December 2023 Security Maintenance Release)
- Check your current Samsung device model and carrier variant
- Navigate to Settings > Software update on your Samsung device
- Tap 'Download and install' to check for available updates
- Ensure the update to SMR Dec-2023 Release 1 (December 2023 security patch level) is installed
- Verify the update was successful by checking Settings > Software update > Software version or Settings > About phone > Software information
