CVE-2024-47039

Local information disclosure via unchecked boot-slot index

Published Dec 18, 2024 · Updated Dec 18, 2024

Out-of-bounds read in Android 10 BootControl allows local users to disclose information through an invalid boot-slot query. The isSlotMarkedSuccessful method in BootControl.cpp passes the slot index to the boot-control module without first checking that it is within the valid slot range. Exploitation requires local access to an affected Pixel device, needs no additional execution privileges or user interaction, and is limited to information disclosure.
