Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.10.6

Description The issue concerns the TCP stack in the Linux kernel, which improperly handles the SCM TIMESTAMPING OPT STATS feature. This mishandling allows local users to either obtain sensitive information from the kernel's internal socket data structures or cause a denial of service through an out-of-bounds read. The issue is related to the net/core/skbuff.c and net/socket.c files.

Recommendations For Linux kernel versions prior to 4.10.6, update to version 4.10.6 or later to resolve the issue.
