Detailsinfo

A vulnerability was found in Linux Kernel (Operating System) (unknown version). It has been classified as problematic. This affects an unknown code block of the file drivers/hid/hid-lenovo-tpkbd.c of the component lenovo-tpkbd HID Driver. The manipulation of the argument CONFIG_HID_LENOVO_TPKBD with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. The summary by CVE is:

drivers/hid/hid-lenovo-tpkbd.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LENOVO_TPKBD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

The weakness was presented 08/28/2013 by Kees Cook with Google Inc. as Linux HID security flaws as not defined mailinglist post (oss-sec). The advisory is shared at seclists.org. This vulnerability is uniquely identified as CVE-2013-2894 since 04/11/2013. The exploitability is told to be difficult. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
