Memory corruption via Audio metadata integer overflow
Published Sep 5, 2023 · Updated Aug 2, 2024
Integer overflow in Qualcomm Snapdragon Audio firmware allows local administrators to corrupt memory through crafted metadata. The Audio metadata validation and mapping path performs overflow-prone arithmetic before mapping metadata, but Qualcomm has not disclosed the affected function or operands. Exploitation requires high local privileges and can compromise confidentiality, integrity, or availability within the affected firmware context.
