Description

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.

Affected configurations

• linux linux kernel (>= 4.9 < 4.19.314) • linux linux kernel (>= 4.20 < 5.4.276) • linux linux kernel (>= 5.5 < 5.10.217) • linux linux kernel (>= 5.11 < 5.15.159) • linux linux kernel (>= 5.16 < 6.1.91) • linux linux kernel (>= 6.2 < 6.6.31) • linux linux kernel (>= 6.7 < 6.8.10) • linux linux kernel 6.9 • debian debian linux 10.0
