Remote denial of service via uninitialized pointer
Published Jan 21, 2021 · Updated Aug 4, 2024
Snapdragon audio playback in affected Qualcomm chipsets allows remote attackers to cause service instability via an incorrect bit stream. During music playback, an uninitialized heap-memory result leaves pointers uninitialized before dereference, producing instability in the audio component. The record does not specify a required authenticated session or a fixed deployment configuration; exploitation depends on reaching the vulnerable music-playback path, and the documented consequence is service instability rather than a confirmed data disclosure or code-execution capability.
