Vulnerability Name:

CCN-78051

Published:2012-08-26
Updated:2012-08-26
Summary:Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference when handling deletion of directory hierarchies. By executing "rm -rf" on a large directory hierarchy, a local attacker could exploit this vulnerability to cause the kernel to crash.
