Description

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.
