Local compromise via session-sign renewal memory corruption
Published Aug 5, 2024 · Updated Aug 15, 2024
Memory corruption in Qualcomm Snapdragon HLOS firmware allows local users to compromise confidentiality, integrity, and availability. Session-sign renewal request handling performs an out-of-bounds memory operation, but Qualcomm has not disclosed the affected function or exact write. A low-privileged local context is required, and successful exploitation can expose or alter data and interrupt device operation.
