Detailed vulnerability description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper access restrictions within the nf_tables_newset() function in net/netfilter/nf_tables_api.c when setting timeouts from userspace. A local user can bypass implemented security restrictions and perform a denial of service attack.
