DescriptionCVE.org

Improper handling of insufficient permissions in Routines prior to SMR May-2026 Release 1 allows local attackers to access sensitive information.

AnalysisAI

Improper permission handling in the Routines automation feature on Samsung Mobile Devices exposes sensitive information to local attackers without requiring elevated privileges. Affected devices run Samsung One UI on Android 15 and Android 16, prior to the SMR May-2026 Release 1 security update. No public exploit has been identified at time of analysis, and CISA's SSVC framework classifies current exploitation as none, consistent with an EPSS score at the 3rd percentile.

Technical ContextAI

The vulnerability resides in Samsung's Routines feature - a built-in One UI automation service allowing users to configure conditional device behaviors - on Android 15 and 16 (CPE: cpe:2.3:a:samsung_mobile:samsung_mobile_devices:*:*:*:*:*:*:*:*). The flaw involves improper handling of permission insufficiency: when the Routines component operates in contexts where its permissions are inadequate, it fails to enforce access restrictions, inadvertently exposing sensitive data to local processes or applications. No CWE was formally assigned by Samsung, but the behavior aligns conceptually with CWE-280 (Improper Handling of Insufficient Permissions or Privileges). The CVSS 4.0 vector AV:L/PR:N/VC:H confirms that the impact is purely a local confidentiality breach with no integrity or availability consequence and no scope change to subsequent systems.

RemediationAI

The definitive fix is to apply SMR May-2026 Release 1, available for Android 15 and Android 16 through Samsung's over-the-air update mechanism or via the Samsung Security Update portal at https://security.samsungmobile.com/securityUpdate.smsb?year=2026&month=05. Organizations managing Samsung device fleets via MDM or EMM solutions may consider restricting or disabling the Routines application as a compensating control prior to patching, though this eliminates automation functionality and may impact user workflows. Additionally, enforcing policies that prevent installation of untrusted applications reduces the local attacker surface that would be needed to trigger this flaw, with the trade-off of restricting user app flexibility.
