Linux Kernel CPUFreq Proc Handler Integer Handling Vulnerability
A local integer handling vulnerability has been announced in the Linux kernel. It is reported that this vulnerability may be exploited by an unprivileged local user to obtain kernel memory contents. Additionally it is reported that a root user may exploit this issue to write to arbitrary regions of kernel memory, which may be a vulnerability in non-standard security enhanced systems where uid 0 does not have this privilege. The vulnerability presents itself due to integer handling errors in the proc handler for cpufreq. |
