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

Description The issue is related to a kernel warning that occurs when sending a SYN message. The warning is caused by a lack of copy direction from the iterator viewpoint, which leads to a kernel stack trace. This is due to a commit that introduced sanity checks for copying from/to iov iterator. The issue is fixed by initializing the iov iterator with the correct copy direction when sending SYN or ACK without data.

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