Linux kernel netfilter do_replace integer overflow
| linux-netfilter-doreplace-overflow (25400) |  High Risk |
Description:
Linux kernel is vulnerable to an integer overflow in the Netfilter do_replace() function. A local attacker with CAP_NET_ADMIN rights could exploit this vulnerability to cause a buffer overflow in the copy_from_user() function and possibly execute arbitrary commands on the system with elevated privileges.
