Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/i915/gem: Fix phys BO pread/pwrite with offset<br />
<br />
sg_page() returns struct page pointer not (void *) so the scaling<br />
of pread/pwrite is wrong for phys BO and wrong parts of BO would be<br />
accessed if non-zero offset is used.<br />
<br />
Last impacted platform with overlay or cursor planes using phys<br />
mapping was Gen3/945G/Lakeport.<br />
<br />
(cherry picked from commit 3e49a2f85070b2fb672c1e0fdba281a4ea3aebe6)
