WMMon Memory Character File Open File Descriptor Read Vulnerability

It has been reported that wmmon is vulnerable to a leakage of open file descriptors that may result in unauthorized disclosure of kernel memory. It is allegedly possible for attackers to inherit the open file descriptors for /dev/mem and /dev/kmem by executing a malicious program through wmmon. The program that is executed can be specified by the attacker at the command line.
