CVE-2016-9313

Priority
Description
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.
Ubuntu-Description
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).
