CRITICAL 10.0

DescriptionCVE.org

In MmsSmsProvider of MmsSmsProvider.java, there is a possible way to retrieve sensitive information due to a missing permission check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

AnalysisAI

Local information disclosure in Android's MmsSmsProvider component allows installed applications to read sensitive SMS/MMS data without holding the required permissions. The flaw stems from a missing permission check inside MmsSmsProvider.java, enabling any local app to query the content provider and exfiltrate message data without user interaction. No public exploit identified at time of analysis, and the issue is addressed in the Android Security Bulletin for Android 17.

Technical ContextAI

MmsSmsProvider is the Android ContentProvider that brokers access to combined SMS and MMS message data stored on the device, normally gated by READ_SMS and related signature/dangerous permissions. The vulnerability is a classic missing-authorization flaw (CWE-862-class - though CWE is reported as N/A here) where one or more query paths in MmsSmsProvider.java fail to enforce the permission check before returning data. Affected CPE is cpe:2.3:a:google:android:*:*:*:*:*:*:*:*, indicating the AOSP framework rather than an OEM-specific build, and the fix flows through the standard monthly bulletin.

RemediationAI

Patch available per vendor advisory: apply the Android 17 security patch level documented at https://source.android.com/docs/security/bulletin/android-17 as soon as the OEM distributes it for the affected device. On managed fleets, raise the minimum patch level in MDM compliance policy to the bulletin date that lists CVE-2026-28587 and quarantine devices that cannot update. Until devices are patched, restrict installation of untrusted third-party apps (enforce Play Protect, disable sideloading via MDM) and consider moving SMS-based 2FA to an authenticator app or hardware key, since SMS contents are exactly what this flaw leaks; the trade-off is user friction for sideloading workflows and 2FA re-enrollment effort.
