Linux kernel is vulnerable to denial of service (DOS) attacks. This is because the NFSv4 server in the Linux kernel does not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-lockup the system and thus cause an application crash.
