Description

A flaw was found in the Linux kernel's bpf programs. Under certain conditions, when the kernel attempts to initiate a network connection using the kernel_connect function, it can return a value that causes the cx_tcp_setup_socket function to loop. This issue can lead to continuous data writing to the Syslog, filling up the available space and causing the kernel to freeze and become unresponsive.
