In the Linux kernel, the following vulnerability has been resolved:
netfilter: complete validation of user input In my recent commit, I missed
that do_replace() handlers use copy_from_sockptr() (which I fixed),
followed by unsafe copy_from_sockptr_offset() calls. In all functions, we
can perform the @optlen validation before even calling
xt_alloc_table_info() with the following check: if ((u64)optlen <
(u64)tmp.size + sizeof(tmp)) return -EINVAL;
