A fix is available — apply it.

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

tracing: Do not call map->ops->elt_free() if elt_alloc() fails

In paths where tracing_map_elt_alloc() failed to allocate objects, the map->ops->elt_alloc() call was never successful. In this case, map->ops->elt_free() should not be called.
