CVE-2023-30645
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 · uneditedHeap out of bound write vulnerability in IpcRxIncomingCBMsg of RILD prior to SMR Jul-2023 Release 1 allows attackers 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 confidenceHeap out-of-bounds write vulnerability in the IpcRxIncomingCBMsg function of RILD (Radio Interface Layer Daemon) allows attackers to execute arbitrary code via malformed IPC callback messages. The vulnerability exists in the inter-process communication handling for radio messages.

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.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is 11.0, 12.0, or 13.0 (these are the affected versions)
-
Confirm device is SamsungCheck the device manufacturer via Settings > About Phone > Manufacturer, or run 'getprop ro.build.brand' via ADB shellAffected if Brand is not Samsung (this vulnerability is specific to Samsung firmware)
-
Check security patch levelRun 'getprop ro.build.version.security_patch' via ADB shell, or check Settings > About Phone > Security patch levelAffected if Patch level is earlier than July 2023 (the vulnerability was patched in Samsung SMR Jul-2023 Release 1)
-
Verify RILD daemon presenceRun 'ps -A | grep rild' via ADB shell to check if the Radio Interface Layer Daemon is runningAffected if RILD is present and running (this is the vulnerable component)
Device is affected if it is a Samsung Android device running version 11.0, 12.0, or 13.0 with a security patch level earlier than July 2023, as the vulnerability exists in the RILD daemon's IPC message handling.

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 Samsung SMR Jul-2023 Release 1 or later security patch to affected devices. This is a vendor-specific vulnerability requiring the manufacturer firmware update.
Samsung SMR Jul-2023 Release 1 or later for Android 11, 12, and 13
- Check your current Android version and Samsung security patch level in Settings > About Phone > Software Information
- Navigate to Settings > Software Update and tap 'Download and install' to check for available updates
- Ensure you update to Samsung's SMR (Security Maintenance Release) Jul-2023 Release 1 or later which contains the fix for the RILD vulnerability
- After updating, verify the security patch level reflects July 2023 or later in Settings > About Phone > Software Information
