Kernel memory corruption via DSP-controlled transfer buffer
Published Jan 21, 2020 · Updated Aug 4, 2024
Out-of-bounds access in Qualcomm Snapdragon FastRPC HLOS Driver allows local users to corrupt kernel memory via DSP-controlled data. During APPS-to-DSP transfers, the driver fails to enforce the DSP-controlled data buffer's bounds before accessing APPS-side kernel memory. Exploitation requires local low-privileged access capable of influencing the DSP buffer; the corruption permits data disclosure, modification, and device interruption.
