CVE-2022-40525

Protected-information disclosure via firmware side channel

Published Jun 6, 2023 · Updated Aug 3, 2024

Information disclosure in Qualcomm Snapdragon networking firmware allows local users to obtain protected information through a side channel. During side-channel analysis, TZ firmware exposes information outside its authorized security sphere; Qualcomm has not disclosed the implicated function or data path. Local code execution on a device containing a listed chipset is required, and the documented consequence is limited to confidentiality.
