Red Hat Update for kernel (RHSA-2016:1640)——漏洞银行丨0DAY BANK

漏洞类别:RedHat

漏洞等级:

漏洞信息

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* A flaw was found in the way certain interfaces of the Linux kernel’s Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system. (CVE-2016-4565, Important)
