CVE-2024-50024

Kernel crash via unsafe listener-list iteration

Published Oct 21, 2024 · Updated Aug 5, 2026

Memory corruption in Linux 2.6.32 through 6.11.3 allows local users to crash the kernel during generic-netlink family removal. The __netlink_clear_multicast_users function uses non-safe list iteration even though netlink_update_socket_mc removes the current mc_list element, leaving traversal on an unlinked node. A local user can seed listeners, but an administrator must unload the providing module; the demonstrated consequence is a kernel crash.
