Stephan Mueller eea0d3ea75 crypto: drbg - set freed buffers to NULL ... During freeing of the internal buffers used by the DRBG, set the pointer to NULL. It is possible that the context with the freed buffers is reused. In case of an error during initialization where the pointers do not yet point to allocated memory, the NULL value prevents a double free.
