The risk

CISA lists CVE-2024-4610 as exploited in the wild since 2024-06-12. No edge WAF vendor names it in a changelog, so default managed rules may or may not catch it.

Who is affected

Teams running Arm Ltd Bifrost GPU Kernel Driver (r34p0 through r40p0) and Arm Ltd Valhall GPU Kernel Driver (r34p0 through r40p0).

Next steps

  1. Update to a fixed version (Bifrost GPU Kernel Driver r41p0 and Valhall GPU Kernel Driver r41p0) using the vendor's guidance. developer.arm.com ↗
  2. CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. US federal agencies must act by 2024-07-03.
  3. Review exposed instances for signs of compromise: it was exploited before many systems were patched, and a later patch does not undo access already gained.
  4. Do not rely on WAF defaults: no edge vendor names this CVE. Restrict access to the vulnerable component or add a custom rule until it is patched. Edge coverage
  5. Check which WAF sits in front of your site and whether it covers this CVE. Check your domain

Radar groups Cloudflare's WAF managed rules by category; it does not publish counts per CVE. These shares show how much attack traffic targets this kind of flaw across Cloudflare's network (28-day trend). They are not compromised systems, and seeing few attempts on Cloudflare does not prove an absence elsewhere. Radar data as of 2026-11-03. Radar ↗

Check your exposure with an agent

Read-only

Copy this into an agent with access to your infrastructure. It asks for an evidence-based, read-only assessment: affected systems, exposure, compensating controls and what is still unknown. It does not scan or change anything by itself.

Prompt12 lines
Assess whether the infrastructure available to you is affected by CVE-2024-4610 (Arm Mali GPU Kernel Driver Use-After-Free Vulnerability). Perform a read-only assessment within your authorized access. Do not send exploit traffic, scan third-party systems, change configuration or restart services.

1. Verify the CVE record at https://www.cve.org/CVERecord?id=CVE-2024-4610 and the vendor advisory. Establish affected and fixed versions, including vendor backports. The record lists: Arm Ltd Bifrost GPU Kernel Driver: affected r34p0 through r40p0; fixed r41p0 | Arm Ltd Valhall GPU Kernel Driver: affected r34p0 through r40p0; fixed r41p0. Cite sources and retrieval dates; flag anything you cannot verify.
2. Inventory deployments of Arm Mali GPU Kernel Driver: asset, environment, owner where known, installed version or build, and how you confirmed it (package metadata, a version endpoint, image tags). An image tag alone does not prove the running version.
3. Identify which deployments are reachable from the internet or untrusted networks, and through which paths (direct origin, load balancer, CDN or WAF).
4. Assess compensating controls separately from patch status. Current edge WAF coverage for this CVE: no edge WAF vendor names it. Live data: https://cve.vigilbase.com/api/v1/cves/CVE-2024-4610. Check whether the rule is enabled and in block mode on each path, and whether any path bypasses the WAF. A WAF rule is not a patch.
5. It is known exploited (CISA KEV): review logs on exposed instances for signs of exploitation before and after patching.

Return a short summary and a table: asset | version/build | assessment (affected, fixed, not applicable, unknown) | exposure | compensating control | evidence | next action. List what you could not assess and the access needed to resolve it. Do not infer absence of compromise from patch status or a lack of alerts.

Remediation guidance: Update to a fixed version (Bifrost GPU Kernel Driver r41p0 and Valhall GPU Kernel Driver r41p0) using the vendor's guidance. CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. US federal agencies must act by 2024-07-03.

Vendor statements

Quoted
CloudflareWAF Managed RulesBefore feed history

The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.

AWSAWS WAF Managed RulesNo public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. AWS often describes a vulnerability without naming its CVE (for example "Log4j"). We count only entries that name the CVE, so AWS coverage is understated.

Microsoft AzureFront Door and Application Gateway WAF (DRS)No public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. The rule tables name CVEs but carry no dates, so Azure is left out of every time-to-rule figure.

Google CloudCloud Armor preconfigured WAF rulesNo public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. Google names few CVEs: the release notes start in May 2024 and the rules reference lists CVEs without dates. Its cve-canary rules are opt-in.

FastlyNext-Gen WAF virtual patchesBefore feed history

The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.

F5Attack signatures (Distributed Cloud WAF)No public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. Each signature lists the CVEs it references, with its id and date. F5 does not state a default action; signatures enforce once staging ends in your policy.

AkamaiApp & API Protector (Adaptive Security Engine)No public source

This vendor publishes no machine-readable rule changelog we can check.

OWASP CRSCore Rule Set (open source, used inside many WAFs)No public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. CRS rarely names CVEs: it relies on generic detections. Our own lab measures what it actually blocks.
