CVE-2026-64231
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dsi: don't dump registers past the mapped region
On DSI 6G platforms the IO address space is internally adjusted by io_offset. Later this adjusted address might be used for memory dumping. However the size that is used for memory dumping isn't adjusted to account for the io_offset, leading to the potential access to the unmapped region. Lower ctrl_size by the io_offset value to prevent access past the mapped area.
