1093076: CVE-2014-3122 Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking
It was found that the try_to_unmap_cluster() function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUG_ON() macro in the mlock_vma_page() function. A local, unprivileged user could use this flaw to crash the system.
