CVE-2014-0069 is a memory corruption vulnerability in the Linux kernel's CIFS file system, specifically within the cifs_iovec_write function, affecting versions through 3.13.5, including Red Hat and SUSE distributions. This flaw allows local users to trigger a system crash, leak sensitive kernel memory, or potentially escalate privileges by crafting a writev system call during uncached write operations. With a CVSS score of 7.2, it is considered high severity due to its low attack complexity and potential for complete compromise of confidentiality, integrity, and availability. There is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is there evidence of active exploitation or significant community discussion surrounding this CVE.

CVE-2014-0069
Jun 11, 2024kernel: cifs: incorrect handling of bogus user pointers during uncached writes
Feb 14, 2014The 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.
