漏洞信息
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):

A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important)
