Memory corruption via concurrent modem restart
Published Jan 21, 2020 · Updated Aug 4, 2024
Heap use-after-free in Qualcomm Snapdragon DPL initialization allows local users to corrupt memory during a concurrent modem restart. The DPL initialization path obtains a datad IPC handle while modem subsystem restart frees the same heap-backed state, leaving stale memory in use. Exploitation requires local low-privileged access and precise restart timing; public records identify neither a remote trigger nor a specific post-corruption outcome.
