Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ila: call nf_unregister_net_hooks() sooner syzbot found an use-after-free Read in ila_nf_input [1] Issue here is that ila_xlat_exit_net() frees the rhashtable, then call nf_unregister_net_hooks(). It should be done in the reverse way, with a synchronize_rcu(). This is a good match for a pre_exit() method.
