Local memory disclosure via unchecked audio payload size
Published Jun 22, 2020 · Updated Aug 4, 2024
Improper input validation in Qualcomm Snapdragon audio firmware allows local users to read memory through an oversized payload. The audio component reads memory without first validating the payload size, so the operation can follow an invalid pointer or return unrelated data. A low-privileged local execution context is required, and the documented consequence is confidentiality loss without integrity or availability impact.
