CVE-2009-2848 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2848): The execve function in unspecified versions of the Linux kernel does not clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.
