Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amdgpu: Fix size validation for non-exclusive domains (v4)<br /> <br /> Fix amdgpu_bo_validate_size() to check whether the TTM domain manager for the<br /> requested memory exists, else we get a kernel oops when dereferencing "man".<br /> <br /> v2: Make the patch standalone, i.e. not dependent on local patches.<br /> v3: Preserve old behaviour and just check that the manager pointer is not<br /> NULL.<br /> v4: Complain if GTT domain requested and it is uninitialized--most likely a<br /> bug.
