Local device compromise via QMI allocation overflow
Published Mar 4, 2024 · Updated Aug 26, 2024
Memory corruption in Qualcomm Core Services firmware allows local users to compromise device confidentiality, integrity, and availability. A QMI request for memory from a DHMS-supported subsystem triggers an integer overflow in the allocation path, causing memory corruption. Exploitation requires local low-privileged access to an affected Qualcomm platform; no remote attack path or safer bounded consequence is published.
