USN-2947-3: Linux kernel (Raspberry Pi 2) vulnerabilities

First published: Wed Apr 06 2016(Updated: )

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)
