CVE-2012-3511: Use After Free
First published: Fri Jul 06 2012(Updated: )
A use-after-free flaw has been found in madvise_remove() function in the Linux kernel. madvise_remove() can race with munmap (causing a use-after-free of the vma) or with close (causing a use-after-free of the struct file). An unprivileged local user can use this flaw to crash the system and potentially gain higher privileges.
