The vulnerability of the implementation of the Upper Level Protocol (ULP) in the Linux operating system allows a hacker to enhance their privileges, execute arbitrary code, or cause a service failure.

The vulnerability in the implementation of the Upper Level Protocol ULP in the Linux kernel’s inetconnectionsock.c file is related to improper handling of sockets that are in the LISTEN state in certain protocols. This leads to the reallocation of previously freed memory. Exploiting this...
