Red Hat Bugzilla – Bug 1000494
CVE-2013-2896 Kernel: HID: ntrig: NULL pointer dereference
Last modified: 2016-03-04 07:44:14 EST
Linux kernel built with the Human Interface Device bus(CONFIG_HID) along with
the N-Trig touch screen driver(CONFIG_HID_NTRIG) support is vulnerable to a
NULL pointer dereference flaw. It could occur when an HID device sends
malicious output report to the ntrig kernel driver.
A local user with physical access to the system could use this flaw to crash
the kernel resulting in DoS.
This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6.
This issue affects the version of the kernel package as shipped with Red Hat Enterprise MRG 2. Future kernel updates for Red Hat Enterprise MRG 2 may address this issue.
Note: user would need physical access to the system to exploit this issue.
