CVE-2022-22080

Local memory corruption via invalid backend ID

Published Sep 2, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Snapdragon PCM routing process in Qualcomm Snapdragon chipsets allows local users to cause memory corruption via crafted backend IDs. The routing process fails to validate a backend identifier before using it, enabling an out-of-range pointer operation that corrupts memory. Exploitation requires local access to a device running affected Snapdragon firmware; the resulting corruption can affect confidentiality, integrity, and availability, but no remote network path is described.
