Description
A flaw was found in the drm/amdgpu component of the Linux kernel. A local attacker, with the ability to issue ioctl commands to the render group, could trigger a null pointer dereference by requesting mapping information for an unmapped buffer object. This could lead to a system crash, resulting in a denial of service.
Statement
This issue affects AMDGPU GEM ioctl. GET_MAPPING_INFO does not check amdgpu_vm_bo_find() NULL result. Systems without AMD GPUs are not affected.
