Summary
linux-lts-wily vulnerabilities
Details

Ralf Spenneberg discovered that the usbvision driver in the Linux kernel did not properly validate the interfaces and endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). (CVE-2015-7833)

Venkatesh Pottem discovered a use-after-free vulnerability in the Linux kernel's CXGB3 driver. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2015-8812)

Xiaofei Rex Guo discovered a timing side channel vulnerability in the Linux Extended Verification Module (EVM). An attacker could use this to affect system integrity. (CVE-2016-2085)

It was discovered that the extended Berkeley Packet Filter (eBPF) implementation in the Linux kernel did not correctly compute branch offsets for backward jumps after ctx expansion. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-2383)

David Herrmann discovered that the Linux kernel incorrectly accounted file descriptors to the original opener for in-flight file descriptors sent over a unix domain socket. A local attacker could use this to cause a denial of service (resource exhaustion). (CVE-2016-2550)

It was discovered that the Linux kernel did not enforce limits on the amount of data allocated to buffer pipes. A local attacker could use this to cause a denial of service (resource exhaustion). (CVE-2016-2847)
