Linux kernel built with the Human Interface Device support(CONFIG_HID), along
with the Lenovo ThinkPad USB Keyboard with TrackPoint(CONFIG_HID_LENOVO_TPKBD)
driver is vulnerable to a heap overflow flaw. It could occur when an HID device
sends malicious output report to the kernel driver.
A local user with physical access to the system could use this flaw to crash
the kernel resulting in DoS or potential privilege escalation to gain root
access via arbitrary code execution.
Statement:
This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
Note: user would need physical access to a system to exploit this flaw.
