Technical description

In the Linux kernel, the following vulnerability has been resolved:

bpf: Check validity of link->type in bpf_link_show_fdinfo()

If a newly-added link type doesn't invoke BPF_LINK_TYPE(), accessing

bpf_link_type_strs[link->type] may result in an out-of-bounds access.

To spot such missed invocations early in the future, checking the

validity of link->type in bpf_link_show_fdinfo() and emitting a warning

when such invocations are missed.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
