Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/msm/dsi: don&#39;t dump registers past the mapped region<br />
<br />
On DSI 6G platforms the IO address space is internally adjusted by<br />
io_offset. Later this adjusted address might be used for memory dumping.<br />
However the size that is used for memory dumping isn&#39;t adjusted to<br />
account for the io_offset, leading to the potential access to the<br />
unmapped region. Lower ctrl_size by the io_offset value to prevent<br />
access past the mapped area.<br />
