What to do

AI-suggested

A fix has been implemented in the Linux kernel to remap EPERM to ECONNREFUSED in xs_tcp_setup_socket(), preventing the infinite loop. Users should apply the official kernel updates that include this fix. Since this is a kernel-level issue, upgrading to a patched kernel version is the recommended mitigation.

Description

CVE-2024-42246 is a vulnerability in the Linux kernel's net and sunrpc subsystems where the xs_tcp_setup_socket() function can enter an infinite loop if a BPF program on kernel_connect() returns -EPERM. This causes excessive syslog flooding and may lead to kernel freeze. The issue arises because -EPERM is not properly remapped to a more expected network error code, causing improper error handling.
