Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the CDC-NCM component in the Linux kernel, where a broken device may provide an extreme offset and a reasonable length for a fragment, causing an integer overflow in the sanity check. This defeats the sanity check, allowing potential exploitation. The quantities offset and offset + len should be checked to prevent overflow, and these quantities should be unsigned.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
