Out-of-bounds memory access via unvalidated audio input
Published Nov 22, 2024 · Updated Nov 22, 2024
Improper input validation in Qualcomm Snapdragon audio firmware allows local users with high privileges to access memory out of bounds. The audio module uses user-provided input for a memory access without adequate validation, causing access beyond the intended bounds; Qualcomm has not disclosed the function or input field. The local high-privilege gate limits reachability, and Qualcomm has not specified whether the resulting access reads, writes, or interrupts service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
