Name of the Vulnerable Software and Affected Versions Android versions 7.0 through 8.1

Description A permissions bypass issue exists due to a missing permission check in the GetPermittedAccessibilityServicesForUser function of DevicePolicyManagerService.java. This could lead to local escalation of privilege, with no additional permissions required. User interaction is not needed for exploitation.

Recommendations For Android versions 7.0 through 8.1, apply the necessary patch to fix the missing permission check in the GetPermittedAccessibilityServicesForUser function of DevicePolicyManagerService.java. As a temporary workaround, consider restricting access to the DevicePolicyManagerService until a patch is available.
