Description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ipset: Hold module reference while requesting a module

User space may unload ip_set.ko while it is itself requesting a set type backend module, leading to a kernel crash. The race condition may be provoked by inserting an mdelay() right after the nfnl_unlock() call.
