Details

Mikulas Patocka discovered that the asynchronous multibuffer cryptographic
daemon (mcryptd) in the Linux kernel did not properly handle being invoked
with incompatible algorithms. A local attacker could use this to cause a
denial of service (system crash). (CVE-2016-10147)

Qidan He discovered that the ICMP implementation in the Linux kernel did
not properly check the size of an ICMP header. A local attacker with
CAP_NET_ADMIN could use this to expose sensitive information.
(CVE-2016-8399)
