Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.14% 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: Within 30 daysRemediation target: Within 180 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
A flaw was found in the Linux kernel's t7xx WWAN driver. A malicious, buggy, or compromised modem firmware can exploit this by sending packets with excessive fragments. This leads to a buffer overflow in the `skb_shinfo(skb)->frags[]` array, corrupting adjacent memory. This can result in kernel crashes or other undefined behavior, effectively causing a Denial of Service (DoS).
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.

01

What, why and how

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: fix potential skb->frags overflow in RX path When receiving data in the DPMAIF RX path, the t7xx_dpmaif_set_frag_to_skb() function adds page fragments to an skb without checking if the number of fragments has exceeded MAX_SKB_FRAGS. This could lead to a buffer overflow in skb_shinfo(skb)->frags[] array, corrupting adjacent memory and potentially causing kernel crashes or other undefined behavior. This issue was identified through static code analysis by comparing with a similar vulnerability fixed in the mt76 driver commit b102f0c522cf ("mt76: fix array overflow on receiving too many fragments for a packet"). The vulnerability could be triggered if the modem firmware sends packets with excessive fragments. While under normal protocol conditions (MTU 3080 bytes, BAT buffer 3584 bytes), a single packet should not require additional fragments, the kernel should not blindly trust firmware behavior. Malicious, buggy, or compromised firmware could potentially craft packets with more fragments than the kernel expects. Fix this by adding a bounds check before calling skb_add_rx_frag() to ensure nr_frags does not exceed MAX_SKB_FRAGS. The check must be performed before unmapping to avoid a page leak and double DMA unmap during device teardown.

Why

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

How

An attacker operating through local access may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

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
local access → Missing Release of Memory after Effective Lifetime → disrupt the affected service

JVN iPedia · Japanese · JVNDB-2026-007864LinuxのLinux Kernelにおける有効期限後のメモリの解放の欠如に関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。net: wwan: t7xxのRXパスでskb-fragsのオーバーフローの可能性が修正されました。DPMAIFのRXパスでデータを受信する際、t7xx_dpmaif_set_frag_to_skb()関数は、断片の数がMAX_SKB_FRAGSを超えていないか確認せずにskbにページ断片を追加していました。これにより、skb_shinfo(skb)-frags[]配列のバッファオーバーフローが発生し、隣接メモリの破損やカーネルのクラッシュ、その他の未定義動作を引き起こす可能性がありました。この問題は、mt76ドライバのコミットb102f0c522cf（"mt76: パケットの断片が多すぎる受信時の配列オーバーフロー修正"）と比較した静的コード解析で特定されました。脆弱性はモデムファームウェアが過剰な断片を持つパケットを送信した場合に発生する可能性があります。通常のプロトコル条件（MTU 3080バイト、BATバッファ3584バイト）では単一パケットが追加断片を必要としませんが、カーネルはファームウェアの動作を盲目的に信頼すべきではありません。悪意ある、バグのある、あるいは改ざんされたファームウェアは、カーネルの想定を超える断片を持つパケットを作成する可能性があります。これを修正するため、skb_add_rx_frag()を呼び出す前にnr_fragsがMAX_SKB_FRAGSを超えないことを確認する境界チェックを追加しました。このチェックはページリークやデバイス終了時のDMAアンマップの二重実行を避けるために、アンマップ前に行う必要があります。
