Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.16.3

Description The issue is related to the net/ceph/auth x.c file in Ceph, as used in the Linux kernel. It does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket.

Recommendations For Linux kernel versions prior to 3.16.3, update to version 3.16.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the auth x module to minimize the risk of exploitation.
