Description:
David Mikolajczyk has reported a vulnerability in Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to an error in the "ioperm" system call and allows unprivileged users to gain read and write access to I/O ports in the I/O address range 0x000-0x3FF (0-1023) on a system. This includes access to serial ports, parallel port, diskette drive controller, graphics controller, and keyboard.
Successful exploitation may e.g. allow monitoring of keyboard input.
