Linux kernel vulnerabilities

Description

CAI Qian discovered that shared bind mounts in a mount namespace exponentially added entries without restriction to the Linux kernel's mount table. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-6213) It was discovered that the KVM implementation for x86/x86_64 in the Linux kernel could dereference a null pointer. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the KVM host. (CVE-2016-8630) Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges. (CVE-2016-8633) Marco Grassi discovered that the TCP implementation in the Linux kernel mishandles socket buffer (skb) truncation. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-8645) 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). (CVE-2016-9313) Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation of incoming data. A remote attacker could use this to cause a denial of service (system crash). (CVE-2016-9555)
