Published severityHighOperational priority:Medium, lowered one band.downgradedsince 8 Sep 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 2.43% 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 30 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: net: skbuff: preserve shared-frag marker during coalescing skb_try_coalesce() can attach paged frags from @from to @to. If @from has SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backed frags, but the shared-frag marker is currently lost. That breaks the invariant relied on by later in-place writers. In particular, ESP input checks skb_has_shared_frag() before deciding whether an uncloned nonlinear skb can skip skb_cow_data(). If TCP receive coalescing has moved shared frags into an unmarked skb, ESP can see skb_has_shared_frag() as false and decrypt in place over page-cache backed frags. Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged frags. The tailroom copy path does not need the marker because it copies bytes into @to's linear data rather than transferring frag descriptors.

Summary
A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged binaries and gain root privileges.

Why

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.

JVN iPedia · Japanese · JVNDB-2026-024874LinuxのLinux Kernelにおける不特定の脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。xfrm: iptfs: iptfs_consume_frags()関数内でshared-fragマーカーを保持する問題の修正です。iptfs_consume_frags()は、ページ化されたフラグメントを一つのソケットバッファから別のソケットバッファに転送しますが、SKBFL_SHARED_FRAGフラグを引き継ぐことに失敗していました。これは、CVE-2026-46300でskb_try_coalesce()に対して修正された同じ種類のバグです。読み取り専用のページキャッシュページによってバックされているフラグメントがマージされる場合は、それらの共有状態を示すマーカーを保持する必要があり、これによってESPのインプレース暗号化が安全かどうかを正しく判断できます。skb_try_coalesce()で使用された同じ2行の修正をiptfs_consume_frags()に適用しました。

JVN iPedia · Japanese · JVNDB-2026-017109LinuxのLinux Kernelにおける境界外書き込みに関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。net: skbuffに関する連結処理時に共有フラグマーカーを保持する問題です。skb_try_coalesce()は@fromから@toへページ化されたフラグメントを添付できます。もし@fromにSKBFL_SHARED_FRAGが設定されている場合、結果としてできる@to skbは同じ外部所有もしくはページキャッシュ対応のフラグメントを含みますが、共有フラグマーカーが現在失われています。それにより、後続のインプレースライターが依存する不変条件が破られます。特にESPは、クローンされていない非線形skbがskb_cow_data()をスキップできるかを決定する前にskb_has_shared_frag()をチェックします。TCPの受信連結が共有フラグメントを未マーキングのskbに移動した場合、ESPはskb_has_shared_frag()をfalseと判断し、ページキャッシュ対応フラグメント上にインプレースで復号を行ってしまう可能性があります。skb_try_coalesce()がページ化フラグメントを転送する際にSKBFL_SHARED_FRAGを伝搬させる修正が加えられました。テールルームコピー経路では、バイトを@toの線形データにコピーするためフラグマーカーは不要です。

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: < 3.9, 5.10.257 ≤ 5.10.*, 5.15.208 ≤ 5.15.*, 6.1.174 ≤ 6.1.*, 6.6.141 ≤ 6.6.*, 6.12.91 ≤ 6.12.*, 6.18.33 ≤ 6.18.*, 7.0.10 ≤ 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.
