Red Hat Security Advisory 2012-0481-01
Posted Apr 17, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0481-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Numerous reference count leaks were found in the Linux kernel's block layer I/O context handling implementation. This could allow a local, unprivileged user to cause a denial of service. A flaw was found in the Linux kernel's cifs_lookup() implementation. POSIX open during lookup should only be supported for regular files. When non-regular files pipe or other special files) are opened on lookup, it could cause a denial of service.
