Important: kernel

Issue Overview:

Unsafe second checksum calculation in udp.c:
The Linux kernel allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag. This may create a kernel panic or memory corruption leading to privilege escalation. (CVE-2016-10229)
