Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.14.x through 3.14.1

Description The issue is related to the cma req handler function in the Linux kernel, which attempts to resolve an RDMA over Converged Ethernet (RoCE) address. This can be exploited by remote attackers using crafted network traffic, leading to a denial of service due to an incorrect pointer dereference and system crash.

Recommendations For Linux kernel versions 3.14.x through 3.14.1, consider disabling the cma req handler function as a temporary workaround until a patch is available. Restrict access to the vulnerable module to minimize the risk of exploitation.
