Memory corruption via GSL node query overflow
Published Jun 6, 2023 · Updated Aug 2, 2024
Stack-based buffer overflow in Qualcomm Snapdragon Automotive GPU firmware allows local users to corrupt memory through a GSL node query. The affected GPU code writes beyond a stack buffer while querying a Graphics Support Layer memory node; Qualcomm has not disclosed the responsible function or malformed field. Local access without prior privileges is required; the disclosed consequence is memory corruption, while crash or code-execution outcomes remain unspecified.
