Title
vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check
Summary
In the Linux kernel, the following vulnerability has been resolved: vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check The vdpa_nl_policy structure is used to validate the nlattr when parsing the incoming nlmsg. It will ensure the attribute being described produces a valid nlattr pointer in info->attrs before entering into each handler in vdpa_nl_ops. That is to say, the missing part in vdpa_nl_policy may lead to illegal nlattr after parsing, which could lead to OOB read just like CVE-2023-3773. This patch adds the missing nla_policy for vdpa queue index attr to avoid such bugs.
