Linux Kernel Security Vulnerabilities

The Linux kernel version 3.12 has a security vulnerability. This vulnerability arises from the fact that the fqinit function does not perform an overflow check when calculating quantum and initialquantum. As a result, multiplication operations may result in a zero value under 32-bit arithmetic...
