CVE-2022-40519

Local memory disclosure via Core buffer over-read

Published Jan 6, 2023 · Updated Apr 9, 2025

Out-of-bounds read in Qualcomm Snapdragon Core allows local users to disclose memory contents through an unspecified trigger. Qualcomm identifies a buffer over-read in Core but has not disclosed the affected routine, the input that crosses the buffer boundary, or the data source read past its end. Local execution is required, and the disclosed consequence is memory exposure; the available advisory does not identify the data read.
