Linux Kernel rt6_fill_node function denial of service
| linux-kernel-rt6fillnode-dos (44605) |  Low Risk |
Description:
Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference in the rt6_fill_node function. By sending an IPv6 request when no IPv6 device is in use, a local attacker could cause a kernel OOPS.
