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