What the advisory describes
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.
Source: EUVD (ENISA), in the words of the advisory.
