Severity CVSS v4.0:

Type:
CWE-787

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