Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2017-15116
CWEhttps://cwe.mitre.org/data/definitions/476.html

The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a denial of service (NULL pointer dereference).

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
