Service interruption via ALAC buffer over-read
Published Aug 5, 2024 · Updated Aug 5, 2024
Buffer over-read in Qualcomm Snapdragon audio firmware allows remote attackers to interrupt service during crafted ALAC playback. The audio decoder reads beyond the available buffer while processing ALAC content; Qualcomm has not disclosed the affected function or precise boundary-check failure. No authentication or user interaction is required, and the reported consequence is a transient playback-related service interruption rather than data exposure or modification.
