CVE-2026-74748 netfilter: ipset: fix refcount race between list:set GC and swap

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix refcount race between list:set GC and swap ipsetputbyindex resolved the index to a set pointer under RCU, then took ipsetreflock in ipsetput to decrement set-ref. ipsetswap holds that same lock while swappin...

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...
