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.

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 confidence

Stack out-of-bounds write vulnerability in the IpcRxImeiUpdateImeiNoti function of RILD (Radio Interface Layer Daemon) in Samsung mobile devices prior to SMR Jul-2023 Release 1 allows writing beyond stack buffer boundaries, potentially causing denial of service.

MitigationApply Samsung security update SMR Jul-2023 Release 1 or later to address the vulnerability in RILD. If immediate patching is not possible, restrict device access to trusted networks to reduce exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify device is a Samsung mobile device
    Check manufacturer via Settings > About phone > Manufacturer, or run `getprop ro.product.manufacturer` / `getprop ro.product.brand` in ADB shell
    Affected if Manufacturer is not Samsung (vulnerability only affects Samsung devices)
  2. Confirm Android version is 11.0, 12.0, or 13.0
    Check Settings > About phone > Android version, or run `getprop ro.build.version.release` in ADB shell
    Affected if Android version matches exactly 11.0, 12.0, or 13.0
  3. Check Samsung SMR (Security Maintenance Release) version
    Run `getprop ro.build.version.sem` in ADB shell to retrieve SMR version string; alternatively check Build number in Settings > Software information
    Affected if SMR version is earlier than Jul-2023 Release 1 (format typically shows as SMRxxx where lower numbers indicate older releases)
  4. Verify RILD daemon is present and running
    Run `ps -A | grep rild` in ADB shell to confirm RILD process is active
    Affected if RILD daemon is running (the vulnerability exists in this component)

Device is affected if it is a Samsung mobile device running Android 11.0, 12.0, or 13.0 with an SMR version earlier than Jul-2023 Release 1.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Samsung security update SMR Jul-2023 Release 1 or later to address the vulnerability in RILD. If immediate patching is not possible, restrict device access to trusted networks to reduce exposure.

Recommended fix Moderate confidence

SMR Jul-2023 Release 1 or later

  1. Check for and apply the Samsung security update for July 2023 (SMR Jul-2023 Release 1) or later on your Samsung Android device
  2. On most Samsung devices: Go to Settings > Software update > Download and install
  3. Ensure the device is charged and connected to Wi-Fi before initiating the update
  4. After updating, verify the security patch level in Settings > About phone > Software information shows the July 2023 security patch or later
