Descriptions
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.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rtnetlink: Validación correcta del atributo IFLA_VF_VLAN_LIST anidado. Se supone que cada atributo dentro de un IFLA_VF_VLAN_LIST anidado es una estructura ifla_vf_vlan_info, por lo que el tamaño de dicho atributo debe ser al menos de sizeof(struct ifla_vf_vlan_info), que es de 14 bytes. La validación de tamaño actual en do_setvfinfo es contra NLA_HDRLEN (4 bytes), que es menor que sizeof(struct ifla_vf_vlan_info), por lo que esta validación no es suficiente y un atributo demasiado pequeño podría convertirse en una estructura ifla_vf_vlan_info, esto podría resultar en un acceso de lectura fuera de banda al acceder a la entrada guardada (transmitida) en ivvl.
