Ubuntu.comUB:CVE-2024-36017CVE-2024-36017
In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation Each
attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a struct
ifla_vf_vlan_info so the size of such attribute needs to be at least of
sizeof(struct ifla_vf_vlan_info) which is 14 bytes. The current size
validation in do_setvfinfo is against NLA_HDRLEN (4 bytes) which is less
than sizeof(struct ifla_vf_vlan_info) so this validation is not enough and
a too small attribute might be cast to a struct ifla_vf_vlan_info, this
might result in an out of bands read access when accessing the saved
(casted) entry in ivvl.
