Unverified pass-through AT commands across Binder boundary

IdentifiersCVE-2026-50207CWE-22· Improper Limitation of a Pathname…

CVE-2026-50207 is a local privilege abuse issue in which a system Binder boundary accepts unverified pass-through AT commands from local applications. Because the Binder-exposed interface does not properly validate or restrict these modem/baseband-directed commands, a locally running application with low privileges can issue AT commands that should not be available to it. According to the provided description, successful exploitation allows reading baseband files and disabling cellular connectivity. The available information does not identify the specific vulnerable function or component beyond the Binder boundary handling pass-through AT commands.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a local application to interact with modem/baseband functionality beyond its intended authorization. The stated impacts are unauthorized access to baseband files, which can expose sensitive modem-related data, and the ability to disable cellular connectivity, causing loss of service. The supplied CVSS v4 metadata indicates high confidentiality, integrity, and availability impact.

Mitigation

If you can’t patch tonight, do this now.

Until a patch is applied, reduce exposure by restricting installation and execution of untrusted local applications, hardening app privilege assignment, and limiting access to the affected Binder service where possible. If operationally feasible, disable or gate any diagnostic or engineering interfaces that permit AT command passthrough to the baseband. Monitor for anomalous local processes interacting with telephony/modem Binder services and for unexpected loss of cellular connectivity.

Remediation

Patch, then assume compromise.

Apply the vendor-provided fix referenced in the CVE record/advisory. Remediation should ensure the Binder-exposed interface no longer accepts unverified pass-through AT commands from untrusted local applications, for example by enforcing strict command allowlisting, caller authorization checks, and removal or restriction of raw AT command passthrough where not required. Review and update affected Acer/Android system components in accordance with the vendor advisory.
