Published severityHighOperational priority:Medium, lowered one band.downgradedsince 17 Sep 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.19% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Linux Linux and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 22 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

24 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 22 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfree_rcu to release ops Florian Westphal says: "Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nf_hook_ops that are used to register the callbacks. However, in v5.14 I added the ability to dump the active netfilter hooks from userspace. This code will peek back into the nf_hook_ops that are available at the tail of the pointer-array blob used by the datapath. The nat hooks are special, because they are called indirectly from the central nat dispatcher hook. They are currently invisible to the nfnl hook dump subsystem though. But once that changes the nat ops structures have to be deferred too." Update nf_nat_register_fn() to deal with partial exposition of the hooks from error path which can be also an issue for nfnetlink_hook.

Summary
A flaw was found in the Linux kernel's netfilter component, specifically within the Network Address Translation (NAT) subsystem. This vulnerability involves improper memory management when releasing network filter operation structures. This could potentially allow an attacker to cause a system crash, leading to a Denial of Service (DoS), or to gain unauthorized access to sensitive information due to the partial exposure of internal hook data during error handling.
Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture. Because of this proactive approach, a patch may be associated with a CVE assignment at a future date. Retroactive CVE assignments are always documented in the corresponding errata and on Red Hat's CVE pages. We strongly advise against delaying updates, as doing so may leave your system exposed when protections are already available.

What, why and how

In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfree_rcu to release ops Florian Westphal says: "Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nf_hook_ops that are used to register the callbacks.

Why

The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path

CWE-763 ↗

CWE-763: Release of Invalid Pointer or Reference. The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.

JVN iPedia · Japanese · JVNDB-2026-023753Linux等の複数ベンダの製品における無効なポインタや参照の解放に関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が解決されました。netfilterのnatにおけるopsの解放にkfree_rcuを使用する問題について、フロリアン・ウェストファル氏は次のように述べています。「歴史的に見ても、通常のベースフックの場合はこれは問題になりません。データパスは、コールバックの登録に使用される元のnf_hook_opsを使用しないためです。しかし、v5.14でユーザースペースからアクティブなnetfilterフックをダンプできる機能が追加されました。このコードは、データパスで使用されるポインター配列の末尾にあるnf_hook_opsを参照します。natフックは特別で、中央のnatディスパッチャーフックから間接的に呼び出されますが、現状ではnfnlフックダンプサブシステムからは見えません。これが将来的に変更される場合、natのops構造体も遅延解放する必要があります。」nf_nat_register_fn()を更新し、エラーパスにおけるフックの部分的露出に対応しました。この問題はnfnetlink_hookにおいても発生する可能性があります。
