What is CVE-2014-0069?
CVE-2014-0069 is a high-severity memory corruption vulnerability in Linux kernel, published on 28 Feb 2014. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer.
