Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation<br /> <br /> Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a<br /> struct ifla_vf_vlan_info so the size of such attribute needs to be at least<br /> of sizeof(struct ifla_vf_vlan_info) which is 14 bytes.<br /> The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes)<br /> which is less than sizeof(struct ifla_vf_vlan_info) so this validation<br /> is not enough and a too small attribute might be cast to a<br /> struct ifla_vf_vlan_info, this might result in an out of bands<br /> read access when accessing the saved (casted) entry in ivvl.
