CVE-2023-30702
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 · uneditedStack overflow vulnerability in SSHDCPAPP TA prior to "SAMSUNG ELECTONICS, CO, LTD. - System Hardware Update - 7/13/2023" in Windows Update for Galaxy book Go, Galaxy book Go 5G, Galaxy book2 Go and Galaxy book2 Pro 360 allows local attacker to execute arbitrary code.
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 · high confidenceA stack overflow vulnerability exists in the SSHDCPAPP Trusted Application (TA) component on Samsung Galaxy book devices running Windows. The overflow occurs when handling specific input, allowing a local attacker to overwrite stack memory and achieve arbitrary code execution with the privileges of the affected component.

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 your Samsung Galaxy Book modelOpen Windows Settings > System > About or run 'systeminfo' in Command Prompt to view the system model nameAffected if Model is Galaxy Book Go, Galaxy Book Go 5G, Galaxy Book2 Go, or Galaxy Book2 Pro 360 (all firmware versions are affected)
-
Check if SSHDCPAPP Trusted Application component is presentInspect the TPM or Trusted Execution Environment (TEE) configuration on the device - this TA is part of Samsung's firmware and runs in the TEE layerAffected if SSHDCPAPP TA component is found running on the system (vulnerable if unpatched)
-
Determine firmware version and patch levelRun 'Get-WmiObject -Class Win32_BIOS' in PowerShell or check Windows Update history for Samsung firmware updatesAffected if Firmware was last updated before July 13, 2023 or has never been updated since purchase
You are affected if you own a Galaxy Book Go, Go 5G, Book2 Go, or Book2 Pro 360 and your firmware has not received the Samsung hardware update released on or after July 13, 2023.
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 · scopedApply the Samsung system hardware update released on July 13, 2023 or later through Windows Update for the affected Galaxy book models (Go, Go 5G, book2 Go, book2 Pro 360).
SAMSUNG ELECTRONICS CO., LTD. - System Hardware Update (7/13/2023) or later
- Navigate to Windows Update on the affected Samsung Galaxy device (Galaxy Book Go, Galaxy Book Go 5G, Galaxy Book2 Go, or Galaxy Book2 Pro 360)
- Check for and install all available System Hardware Updates
- Ensure the update dated 7/13/2023 or later from SAMSUNG ELECTRONICS CO., LTD. is applied
- After updating, verify the SSHDCPAPP TA vulnerability has been addressed by confirming the system is running the patched firmware version
