Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.51% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • 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 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 96 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: nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its callers Currently, when nvmet_tcp_build_pdu_iovec() detects an out-of-bounds PDU length or offset, it triggers nvmet_tcp_fatal_error(cmd->queue) and returns early. However, because the function returns void, the callers are entirely unaware that a fatal error has occurred and that the cmd->recv_msg.msg_iter was left uninitialized. Callers such as nvmet_tcp_handle_h2c_data_pdu() proceed to blindly overwrite the queue state with queue->rcv_state = NVMET_TCP_RECV_DATA Consequently, the socket receiving loop may attempt to read incoming network data into the uninitialized iterator. Fix this by shifting the error handling responsibility to the callers.
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 `nvmet-tcp` component of the Linux kernel. The `nvmet_tcp_build_pdu_iovec()` function fails to propagate errors when detecting out-of-bounds PDU lengths or offsets. This can lead to uninitialized memory being used by subsequent operations, such as reading incoming network data into an uninitialized iterator. A remote attacker could potentially exploit this memory corruption to cause a denial of service or achieve arbitrary code execution.
Remediation
For Red Hat Enterprise Linux, mitigation for this issue is not applicable as the product is not affected. For Red Hat In-Vehicle OS, if the NVM Express over TCP (nvmet-tcp) functionality is not required, the `nvmet_tcp` kernel module can be prevented from loading. To do this, create a file named `/etc/modprobe.d/disable-nvmet-tcp.conf` with the following content: `install nvmet_tcp /bin/true` `blacklist nvmet_tcp` After creating the file, regenerate the initramfs and reboot the system for the changes to take effect. Disabling this module may impact storage functionality if NVMe over TCP is in use.

Why

The product detects a specific error, but takes no actions to handle the error.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. 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-2026-023758LinuxのLinux Kernelにおける複数の脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました：nvmet-tcpのnvmet_tcp_build_pdu_iovec()関数におけるエラーを呼び出し元に伝播するように修正されました。現在、nvmet_tcp_build_pdu_iovec()は範囲外のPDU長またはオフセットを検出すると、nvmet_tcp_fatal_error(cmd-＞queue)を呼び出して早期にリターンします。しかし、この関数はvoidを返すため、呼び出し元は致命的なエラーが発生し、cmd-＞recv_msg.msg_iterが初期化されていないままであることを全く認識できません。例えば、nvmet_tcp_handle_h2c_data_pdu()のような呼び出し元は、queue-＞rcv_state = NVMET_TCP_RECV_DATA と無条件にキューの状態を上書きしてしまいます。その結果、ソケットの受信ループは初期化されていないイテレータにネットワークからの受信データを読み込もうとする可能性があります。この問題を修正するため、エラー処理の責任を呼び出し元に移譲しました。

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: < 6.19, 6.1.175 ≤ 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. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
