CVE-2016-10408

QSEE crash via speculative device-memory fetches

Published Nov 26, 2024 · Updated Nov 26, 2024

Improper access control in QSEE on Qualcomm Snapdragon Mobile chipsets allows local users to crash the trusted execution environment. QSEE speculatively fetches instructions from device-memory regions even though those regions are not executable, producing a fatal execution error. Exploitation requires local access to an affected chipset, and the disclosed behavior interrupts QSEE; no trigger details are public.
