Details

It was discovered that the netfilter netlink implementation in the Linux
kernel did not properly validate batch messages. A local attacker with the
CAP_NET_ADMIN capability could use this to expose sensitive information or
cause a denial of service. (CVE-2016-7917)

Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build()
function in the Linux kernel. A local attacker could use to cause a denial
of service (system crash) or possibly execute arbitrary code with
administrative privileges. (CVE-2016-8632)

It was discovered that the keyring implementation in the Linux kernel in
some situations did not prevent special internal keyrings from being joined
by userspace keyrings. A privileged local attacker could use this to bypass
module verification. (CVE-2016-9604)

It was discovered that a buffer overflow existed in the trace subsystem in
the Linux kernel. A privileged local attacker could use this to execute
arbitrary code. (CVE-2017-0605)

Dmitry Vyukov discovered that KVM implementation in the Linux kernel
improperly emulated the VMXON instruction. A local attacker in a guest OS
could use this to cause a denial of service (memory consumption) in the
host OS. (CVE-2017-2596)

Daniel Jiang discovered that a race condition existed in the ipv4 ping
socket implementation in the Linux kernel. A local privileged attacker
could use this to cause a denial of service (system crash). (CVE-2017-2671)

Di Shen discovered that a race condition existed in the perf subsystem of
the Linux kernel. A local attacker could use this to cause a denial of
service or possibly gain administrative privileges. (CVE-2017-6001)

Eric Biggers discovered a memory leak in the keyring implementation in the
Linux kernel. A local attacker could use this to cause a denial of service
(memory consumption). (CVE-2017-7472)

Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash)
implementation in the Linux kernel did not properly handle a full request
queue. A local attacker could use this to cause a denial of service
(infinite recursion). (CVE-2017-7618)

Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly handle certain long
RPC replies. A remote attacker could use this to cause a denial of service
(system crash). (CVE-2017-7645)

Tommi Rantala and Brad Spengler discovered that the memory manager in the
Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection
mechanism. A local attacker with access to /dev/mem could use this to
expose sensitive information or possibly execute arbitrary code.
(CVE-2017-7889)

Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly check for the end of
buffer. A remote attacker could use this to craft requests that cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2017-7895)

It was discovered that a use-after-free vulnerability existed in the device
driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-7913)

Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO
PCI driver for the Linux kernel. A local attacker with access to a vfio PCI
device file could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084)
