Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.1

Description The issue is related to an integer signedness error in the CIFSFindNext function, which can be exploited by remote CIFS servers. This error occurs when a large length value is included in a response to a read request for a directory, potentially causing a denial of service due to memory corruption. There may be other unspecified impacts as well.
