Summary
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)
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)
