# CVE-2024-58060: bpf: Reject struct_ops registration that uses module ptr and the module btf_id is missing

> A use-after-free in the Linux kernel BPF subsystem allows attackers to execute arbitrary code or escalate privileges when CONFIG_MODULES is disabled.

## What is CVE-2024-58060?

CVE-2024-58060 is a high-severity use after free vulnerability in Linux kernel, published on 6 Mar 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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

bpf: Reject struct_ops registration that uses module ptr and the module btf_id is missing

There is a UAF report in the bpf_struct_ops when CONFIG_MODULES=n.
In particular, the report is on tcp_congestion_ops that has
a "struct module *owner" member.

For struct_ops that has a "struct module *owner" member,
it can be extended either by the regular kernel module or
by the bpf_struct_ops. bpf_try_module_get() will be used
to do the refcounting and different refcount is done
based on the owner pointer. When CONFIG_MODULES=n,
the btf_id of the "struct module" is missing:

WARN: resolve_btfids: unresolved symbol module

Thus, the bpf_try_module_get() cannot do the correct refcounting.

Not all subsystem's struct_ops requires the "struct module *owner" member.
e.g. the recent sched_ext_ops.

This patch is to disable bpf_struct_ops registration if
the struct_ops has the "struct module *" member and the
"struct module" btf_id is missing. The btf_type_is_fwd() helper
is moved to the btf.h header file for this test.

This has happened since the beginning of bpf_struct_ops which has gone
through many changes. The Fixes tag is set to a recent commit that this
patch can apply cleanly. Considering CONFIG_MODULES=n is not
common and the age of the issue, targeting for bpf-next also.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-58060 and fix it if it is affected.

What it is: CVE-2024-58060 is a high-severity use after free vulnerability in Linux kernel, published on 6 Mar 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-58060 in the wild and no public exploit code.

Affected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
