CVE-2021-35105

Local out-of-bounds access via graphics profiling cast

Published Apr 1, 2022 · Updated Aug 4, 2024

Incorrect type conversion in Qualcomm Snapdragon graphics components allows local users to obtain out-of-bounds access during profiling. The graphics profiling path inadequately validates input before converting its type, allowing the resulting value to address memory outside the intended bounds. Exploitation requires local execution on a device containing an affected chipset; public sources do not disclose the exact profiling interface or resulting operation.
