A local attacker could use this to cause a denial of service (resource exhaustion). (CVE-2016-2188) It was discovered that the Linux kernel did not enforce limits on the amount of data allocated to buffer pipes. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-2186) Ralf Spenneberg discovered that the I/O-Warrior USB device driver in the Linux kernel did not properly validate USB device descriptors. (CVE-2016-2185) Ralf Spenneberg discovered that the PowerMate USB driver in the Linux kernel did not properly validate USB device descriptors. (CVE-2016-2184) Ralf Spenneberg discovered that the ATI Wonder Remote II USB driver in the Linux kernel did not properly validate USB device descriptors. (CVE-2016-4557) Ralf Spenneberg discovered that the USB sound subsystem in the Linux kernel did not properly validate USB device descriptors. A local unprivileged attacker could use this to gain administrative privileges. Jann Horn discovered that the extended Berkeley Packet Filter (eBPF) implementation in the Linux kernel did not properly reference count file descriptors, leading to a use-after-free. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Description USN-2965-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS.
