# CVE-2026-49747: GPU DDK - OOB write for mappings larger than 4GB due to integer overflow in PVRDmaBufOpsMapCommon

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

Software installed and run as a non-privileged user may conduct GPU system calls to trigger an integer overflow and allow OOB writes to GPU buffers.



The integer overflow caused when mapping a GPU buffer >4GB causes corruption of array length, and can lead to kernel panics or out of bounds access.
