Medium

Base vector

AV:A/AC:M/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions 2.6.x

Description The issue is related to a race condition in the cm work handler function of the InfiniBand driver. This condition allows remote attackers to cause a denial of service by sending an InfiniBand request while other request handlers are still running, resulting in an invalid pointer dereference.

Recommendations For Linux kernel version 2.6.x, consider disabling the cm work handler function as a temporary workaround until a patch is available. Restrict access to the InfiniBand driver to minimize the risk of exploitation.
