Evidence used

  • CISA confirms exploitation in the wild.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.83% 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.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Linux Kernel 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: Within 3 daysRemediation target: Within 90 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 20 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 20 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: bridge: make ebt_snat ARP rewrite writable The ebtables SNAT target keeps the Ethernet source address rewrite behind skb_ensure_writable(skb, 0). This is intentional: at the bridge ebtables hooks the Ethernet header is addressed through skb_mac_header()/eth_hdr(), while skb->data points at the Ethernet payload. Asking skb_ensure_writable() for ETH_HLEN bytes would check the payload, not the Ethernet header, and would reintroduce the small packet regression fixed by commit 63137bc5882a. However, the optional ARP sender hardware address rewrite is different. It writes through skb_store_bits() at an offset relative to skb->data: skb_store_bits(skb, sizeof(struct arphdr), info->mac, ETH_ALEN) skb_header_pointer() only safely reads the ARP header; it does not make the later sender hardware address range writable. If that range is still held in a nonlinear skb fragment backed by a splice-imported file page, skb_store_bits() maps the frag page and copies the new MAC address directly into it. Ensure the ARP SHA range is writable before reading the ARP header and before calling skb_store_bits().
Remediation
To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".

Summary
A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT (Source Network Address Translation) module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP (Address Resolution Protocol) sender hardware address rewrite. This could lead to unintended system behavior, a denial of service, or potentially local privilege escalation, where an attacker gains higher access rights than intended.
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.

Recommended actionPatch only the product branches with a verified fix

Fix availability varies by product
01

What, why and how

Linux Kernel contains an out-of-bounds write vulnerability in the ebtables SNAT target which allows an ARP sender hardware address rewrite to write directly into a nonlinear socket-buffer fragment backed by a splice-imported file page. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version.

The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version.

Why

A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.

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.

JVN iPedia · Japanese · JVNDB-2026-022875LinuxのLinux Kernelにおける不特定の脆弱性

Linuxカーネルにおいて、以下の脆弱性が解決されました。netfilter: bridge: ebt_snatのARP書き換えを可能にするebtablesのSNATターゲットは、Ethernetソースアドレスの書き換えをskb_ensure_writable(skb, 0)の背後で保持しています。これは意図的なものであり、ブリッジのebtablesフックではEthernetヘッダーがskb_mac_header()やeth_hdr()を通して参照される一方で、skb-＞dataはEthernetペイロードを指しています。skb_ensure_writable()にETH_HLENバイト数を要求するとペイロードが検査され、Ethernetヘッダーではなく、コミット63137bc5882aで修正された小さいパケットの後退が再び発生してしまいます。しかし、任意のARP送信元ハードウェアアドレスの書き換えは異なります。これはskb-＞dataを基準にしたオフセットでskb_store_bits()を通じて書き込みます。具体的には、 skb_store_bits(skb, sizeof(struct arphdr), info-＞mac, ETH_ALEN)が使われます。skb_header_pointer()はARPヘッダーのみを安全に読み取りますが、その後の送信元ハードウェアアドレス範囲をwritableにはしません。その範囲がまだspliceでインポートされたファイルページに裏付けられた非線形skbフラグメント内にある場合、skb_store_bits()はフラグメントのページをマップし、新しいMACアドレスを直接コピーします。ARPのSHA範囲を、ARPヘッダーを読む前およびskb_store_bits()を呼び出す前に書き込み可能にすることが保証されます。

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix availability varies by product
Affected
Fixed
Linux: < 5.10, 5.10.259 ≤ 5.10.*, 5.15.210 ≤ 5.15.*, 6.1.176 ≤ 6.1.*, 6.6.143 ≤ 6.6.*, 6.12.94 ≤ 6.12.*, 6.18.36 ≤ 6.18.*, 7.0.13 ≤ 7.0.*, 7.1 ≤ *
Action
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
No verified workaround is recorded. Limit untrusted access and use least privilege until authoritative guidance is available.
