CVE-2026-74748

CVE-2026-74748 is a refcount race in the Linux kernel's netfilter ipset subsystem. The function __ip_set_put_byindex() resolves a set index under RCU but decrements the reference count only after acquiring ip_set_ref_lock. A concurrent ip_set_swap() call can interleave between these two steps, ca...
