CVE-2023-42680

Local denial of service via unchecked GPU read

Published Dec 4, 2023 · Updated Aug 2, 2024

Out-of-bounds read in the GPU driver for eleven UNISOC chipsets allows local users with System privileges to cause a denial of service. The GPU driver performs a read without checking input-derived bounds, allowing the operation to extend beyond the intended buffer. Exploitation requires local System-level execution and can interrupt the affected Android device; no confidentiality impact is reported.
