Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.13.6

Description The issue is related to a race condition in the Linux kernel, specifically in the net/packet/af packet.c file, which can lead to a use-after-free error when handling packet fanout data structures. This is caused by the interaction between fanout add and packet do bind system calls. The problem allows local users to potentially gain privileges.
