Local data disclosure via ADM payload over-read
Published Jun 2, 2020 · Updated Aug 5, 2024
Out-of-bounds read in Qualcomm Snapdragon audio firmware allows local users to disclose memory or interrupt audio processing. The ADM callback applies an incorrect boundary check to a command-response payload, allowing the callback to read beyond the payload buffer. Exploitation requires low-privileged local access on a device using a listed affected chipset; no memory modification is reported.
