CVE-2023-44123
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 · uneditedThe vulnerability is the use of implicit PendingIntents with the PendingIntent.FLAG_MUTABLE set that leads to theft and/or (over-)write of arbitrary files with system privilege in the Bluetooth ("com.lge.bluetoothsetting") app. The attacker's app, if it had access to app notifications, could intercept them and redirect them to its activity, before making it grant access permissions to content providers with the `android:grantUriPermissions="true"` flag.
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 confidenceVulnerability in the LG Bluetooth app (com.lge.bluetoothsetting) where implicit PendingIntents with FLAG_MUTABLE allow an attacker with notification access to intercept and redirect intents, enabling theft or overwrite of arbitrary files with system privileges and unauthorized access to content providers with grantUriPermissions enabled.

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 ADBAffected if Version is 12.0 or 13.0 exactly (note: only these specific versions are affected)
-
Check if LG Bluetooth app is installedNavigate to Settings > Apps > Show system apps and search for 'Bluetooth Setting' or run 'pm list packages | grep lge.bluetoothsetting' via ADBAffected if Package com.lge.bluetoothsetting is installed on the device
-
Verify notification access configurationGo to Settings > Apps > Special access > Notification access to see which apps have notification listener accessAffected if Any untrusted or unauthorized application has been granted notification access permission
A device is affected if it runs Android 12.0 or 13.0, has the LG Bluetooth app (com.lge.bluetoothsetting) installed, and has an untrusted app with notification access permission that could intercept the vulnerable implicit PendingIntents.

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.
From vendor dataReplace implicit PendingIntents with explicit ones and use FLAG_IMMUTABLE flag; review all PendingIntent usages in the Bluetooth app to prevent intent hijacking and unauthorized content provider access.
