CVE-2016-9313
Published: 27 November 2016
security/keys/big_key.c in the Linux kernel before 4.8.7 mishandles unsuccessful crypto registration in conjunction with successful key-type registration, which allows local users to cause a denial of service (NULL pointer dereference and panic) or possibly have unspecified other impact via a crafted application that uses the big_key data type.
From the Ubuntu Security Team
It was discovered that the keyring implementation in the Linux kernel improperly handled crypto registration in conjunction with successful key- type registration. A local attacker could use this to cause a denial of service (system crash).
