Patch only the product branches with a verified fix

Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority. Verified remediation exists for at least one product or source, but 252 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.12% 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: No default targetRemediation target: Normal maintenance

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 252 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.

25 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: bpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if BPF LSM is uninitialized When CONFIG_BPF_LSM=y is set, BPF inode storage maps (BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However, if the BPF LSM is not explicitly enabled at boot time (e.g. omitted from the "lsm=" boot parameter), lsm_prepare() is never executed for the BPF LSM. Consequently, the BPF inode security blob offset (bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains at its default compiled size of 8 bytes instead of being updated to a valid offset past the reserved struct rcu_head (typically 16 bytes or more). When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGE map, bpf_inode() evaluates inode->i_security + 8. This erroneously aliases the struct rcu_head.func callback pointer at the beginning of the inode->i_security blob. During subsequent map element cleanup or inode destruction, writing NULL to owner_storage clears the queued RCU callback pointer. When rcu_do_batch() later executes the queued callback, it attempts an instruction fetch at address 0x0, triggering an immediate kernel panic. Fix this by introducing a global bpf_lsm_initialized boolean flag marked with __ro_after_init. Set this flag to true inside bpf_lsm_init() when the LSM framework successfully registers the BPF LSM. Gate map allocation in inode_storage_map_alloc() on this flag, returning -EOPNOTSUPP if the BPF LSM is in turn uninitialized. This fail-fast approach prevents userspace from allocating inode storage maps when the supporting BPF LSM infrastructure is absent, avoiding zombie map states.
Remediation

Summary
A flaw was found in the Linux kernel. When the BPF (Berkeley Packet Filter) Linux Security Module (LSM) is compiled into the kernel but not explicitly enabled at boot, a privileged user can create and update a BPF inode storage map. This improper initialization leads to an incorrect memory offset calculation, which can corrupt internal kernel structures. Consequently, this can trigger a kernel panic, resulting in a Denial of Service (DoS) for the system.

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-2026-027869LinuxのLinux KernelにおけるNULL ポインタデリファレンスに関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。bpf: BPF LSMが初期化されていない場合にBPF_MAP_TYPE_INODE_STORAGEの作成を拒否する対策です。CONFIG_BPF_LSM=yが設定されている場合、BPF inodeストレージマップ(BPF_MAP_TYPE_INODE_STORAGE)がカーネルにコンパイルされます。しかし、BPF LSMが起動時に明示的に有効化されていない場合(例えば、「lsm=」ブートパラメータから省略された場合)、lsm_prepare()はBPF LSMに対して一度も実行されません。結果として、BPF inodeセキュリティblobのオフセット(bpf_lsm_blob_sizes.lbs_inode)が初期化されず、予約されたstruct rcu_headの後の有効なオフセット(通常16バイト以上)に更新される代わりに、コンパイル時のデフォルトサイズである8バイトのままとなります。特権ユーザーがBPF_MAP_TYPE_INODE_STORAGEマップを作成および更新すると、bpf_inode()はinode->i_security + 8を評価します。これは誤ってinode->i_security blobの先頭にあるstruct rcu_head.funcコールバックポインタと衝突します。その後のマップ要素のクリーンアップやinodeの破棄時に、owner_storageをNULLに書き込むことでキューに入っているRCUコールバックポインタがクリアされます。rcu_do_batch()が後でキューに入ったコールバックを実行する際、アドレス0x0で命令フェッチを試みるため、即座にカーネルパニックが発生します。これを修正するために、__ro_after_init属性付きのグローバルなbpf_lsm_initializedブールフラグを導入しました。LSMフレームワークがBPF LSMの登録に成功した場合、bpf_lsm_init()内でこのフラグをtrueに設定します。inode_storage_map_alloc()内のマップ割り当てはこのフラグを条件として判定し、BPF LSMが初期化されていない場合は-EOPNOTSUPPを返します。このフェイルファスト方式により、BPF LSMのサポートインフラが存在しない場合にユーザースペースからinodeストレージマップの割り当てを防ぎ、ゾンビマップ状態の発生を回避します。

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
