Memory corruption via untrusted pointer dereference in DSP
Published Aug 6, 2025 · Updated Aug 6, 2025
Untrusted pointer dereference in Qualcomm Snapdragon DSP Service allows local users to corrupt memory through DDI command calls. A DSP Service handler trusts and dereferences a pointer received during DDI command processing, but Qualcomm has not identified the affected function or operation. Access requires a local low-privilege context and no user interaction; the published material does not disclose whether exploitation reads memory, writes memory, executes code, or crashes the service.
