Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amdgpu: Add bounds checking to ib_{get,set}_value<br />
<br />
The uvd/vce/vcn code accesses the IB at predefined offsets without<br />
checking that the IB is large enough. Check the bounds here. The caller<br />
is responsible for making sure it can handle arbitrary return values.<br />
<br />
Also make the idx a uint32_t to prevent overflows causing the condition<br />
to fail.
