CVE-2026-50207
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 system Binder boundary accepts unverified pass-through AT commands, giving local applications the power to read baseband files or disable cellular connectivity.
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 confidenceThis vulnerability exists in Android's Binder inter-process communication mechanism, where the system fails to properly validate AT commands passed through the Binder boundary to the baseband processor. Local applications can exploit this unverified pass-through to send AT commands that allow reading baseband files or disabling cellular connectivity, representing a privilege escalation from normal app permissions to baseband-level control.

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 the firmware version of the Acer Connect M6e 5g deviceAccess the device admin web interface or check through ADB (if developer access is available) and look for the firmware/build version information. This is typically found in Settings > About Device or a dedicated Firmware/Status page.Affected if The installed firmware version is m6e_ai_1.00.000019 or lower.
-
Verify if the Binder interface exposes AT command handlingReview the device's system logs (logcat) for any Binder transactions related to AT command interfaces. Search for entries containing 'AT' or 'baseband' being passed through Binder IPC calls from non-system UIDs.Affected if AT command traffic is observable going through Binder calls accessible from non-privileged app contexts.
-
Confirm whether unprivileged apps can access the baseband AT interfaceAttempt to identify if any application with regular (non-system) Android UID can communicate with the baseband processor through exposed Binder services. This may require static analysis of the device firmware or checking permission configurations.Affected if Applications without SYSTEM or privileged carrier permissions can send commands to the baseband processor.
-
Check for the presence of AT command validation in the Binder serviceIf you have access to the device's decompiled system services, examine the Binder interface code that handles AT command routing. Look for whitelist or validation logic before commands are forwarded to the baseband.Affected if No whitelist or validation check exists on AT commands received through the Binder interface.
A device is affected if it runs Acer Connect M6e 5g firmware at version m6e_ai_1.00.000019 or lower AND unprivileged applications can send AT commands to the baseband through the Binder IPC without validation.

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 dataPatching requires implementing proper validation and authorization checks for AT commands within the Binder IPC handler, likely in the Android framework layer. OEMs should apply security patches from the Android monthly security bulletin that addresses this Binder boundary validation issue.
