Description

In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Use caller client for debug BO sync

amdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's
drm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls
amdxdna_hwctx_sync_debug_bo(), but passes abo->client.

amdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle
namespace for debug_bo_hdl and as the owner of the hardware context xarray.
Those must match the file that supplied args->handle. The BO's stored
client pointer is object state, not the ioctl context.

Pass filp->driver_priv instead, matching the original handle lookup.
