Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: fw_tracer, return NULL on create error Tracer creation can fail by returning either NULL or ERR_PTR. The return value is stored without a check on the device, and users treat ERR_PTR and NULL the same way. This also causes a crash in the core dump logic, which is missing the ERR_PTR check and ends up dereferencing it, as shown in the trace below. Switch tracer creation to return NULL on failure only, so callers only need a single NULL check.
