Published severityMediumOperational priority:Low, lowered one band.downgradedsince 19 Jul 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.16% 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 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: Bluetooth: L2CAP: ecred_reconfigure: send packed pdu, not stack pointer Commit 1c08108f3014 ("Bluetooth: L2CAP: Avoid -Wflex-array-member-not-at-end warnings") converted the on-stack request PDU in l2cap_ecred_reconfigure() from an explicit packed struct to DEFINE_RAW_FLEX(), but did not adjust the size and source-pointer arguments to l2cap_send_cmd(): - struct { - struct l2cap_ecred_reconf_req req; - __le16 scid; - } pdu; + DEFINE_RAW_FLEX(struct l2cap_ecred_reconf_req, pdu, scid, 1); ... l2cap_send_cmd(conn, chan->ident, L2CAP_ECRED_RECONF_REQ, sizeof(pdu), &pdu); After the conversion, DEFINE_RAW_FLEX() expands to declare an anonymous union pdu_u plus a local pointer "pdu" pointing at it. Therefore: - sizeof(pdu) is now sizeof(struct l2cap_ecred_reconf_req *) = 8 on 64-bit (4 on 32-bit), not the 6 bytes of (mtu, mps, scid[1]). - &pdu is the address of the local pointer's stack storage, not the address of the request payload. l2cap_send_cmd() forwards (data, count) to l2cap_build_cmd(), which calls skb_put_data(skb, data, count). The L2CAP_ECRED_RECONFIGURE_REQ packet body therefore contains 8 bytes copied from the kernel stack starting at &pdu -- the 8 bytes overlap the pdu pointer's value, leaking a kernel stack address to the paired Bluetooth peer. The intended (mtu, mps, scid) fields are not transmitted at all, so the peer rejects the request as malformed and the L2CAP_ECRED_RECONFIGURE feature itself has been broken for the local-side initiator since the introducing commit landed. The sibling site l2cap_ecred_conn_req() in the same commit was converted correctly (sizeof(*pdu) + len, pdu); only this site was missed. Restore the original semantics: pass the full flex-struct size via struct_size(pdu, scid, 1) and the pdu pointer (the struct address) as the source. Validated on a stock 7.0-based host kernel via the real call path: setsockopt(SOL_BLUETOOTH, BT_RCVMTU, ...) on a BT_CONNECTED L2CAP_MODE_EXT_FLOWCTL socket emits an L2CAP_ECRED_RECONFIGURE_REQ whose body is 8 bytes (the on-stack pdu local's value) rather than the expected 6. Three captures from fresh socket / fresh hciemu peer on the same host -- low bytes vary per call, high 0xffff confirms a kernel virtual address (KASLR-randomised stack slot, not a fixed string): RECONF_REQ body (ident=0x02 len=8): 42 fb 54 af 0e ca ff ff RECONF_REQ body (ident=0x02 len=8): 52 3d 2e af 0e ca ff ff RECONF_REQ body (ident=0x02 len=8): b2 fc 5b af 0e ca ff ff After this patch the body is 6 bytes carrying the expected little-endian (mtu, mps, scid).

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

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.

02

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-2026-028280Linux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。Bluetooth: L2CAP: ecred_reconfigureにおいて、スタックポインタではなくパックされたPDUが送信される問題です。コミット1c08108f3014("Bluetooth: L2CAP: -Wflex-array-member-not-at-end警告を回避")では、l2cap_ecred_reconfigure()内のスタック上のリクエストPDUを明示的なパック構造体からDEFINE_RAW_FLEX()に変換しましたが、l2cap_send_cmd()へのサイズおよびソースポインタ引数の調整が行われていませんでした。具体的には以下の通りです。- 元のコード: struct { struct l2cap_ecred_reconf_req req; __le16 scid; } pdu;- 変更後コード: DEFINE_RAW_FLEX(struct l2cap_ecred_reconf_req, pdu, scid, 1);...l2cap_send_cmd(conn, chan->ident, L2CAP_ECRED_RECONF_REQ, sizeof(pdu), &pdu);DEFINE_RAW_FLEX()は無名共用体pdu_uの宣言と、それを指すローカルポインタpduの宣言に展開されるため、sizeof(pdu)は64ビット環境で構造体ポインタのサイズ(8バイト)、32ビット環境で4バイトとなり、本来の6バイト(mtu, mps, scid[1]の合計)にはなりません。また、&pduはリクエストペイロードのアドレスではなく、ローカルポインタのスタック上のアドレスを指します。l2cap_send_cmd()は(data, count)をl2cap_build_cmd()に渡し、さらにskb_put_data(skb, data, count)を呼び出します。そのため、L2CAP_ECRED_RECONFIGURE_REQパケット本体はカーネルスタック上の&pduからコピーされた8バイトを含み、そのバイト列はpduポインタの値と重なっており、カーネルスタック上のアドレスがペアリング済みBluetoothピアに漏洩します。本来送信されるべき(mtu, mps, scid)フィールドは全く送信されず、ピアはリクエストを不正として拒否し、このコミット以降ローカル側イニシエータのL2CAP_ECRED_RECONFIGURE機能は破損しました。同じコミット内の兄弟箇所l2cap_ecred_conn_req()は正しく変換されており(sizeof(*pdu) + len, pdu)、本問題はこの箇所のみの見逃しによるものです。修正内容は元の意味論を復元し、構造体の完全なサイズをstruct_size(pdu, scid, 1)で渡し、pduポインタ(構造体のアドレス)を送信元として渡しています。実際の呼び出し経路にて、7.0ベースの標準ホストカーネル上で検証済みです。BT_CONNECTED状態のL2CAP_MODE_EXT_FLOWCTLソケットにsetsockopt(SOL_BLUETOOTH, BT_RCVMTU, ...)を行うと、元の問題では6バイトのはずのL2CAP_ECRED_RECONFIGURE_REQの本体が8バイト(スタック上のpduローカル変数の値)となっていました。ホスト上の新規ソケットと新規HCIエミュレータピアによる3回のキャプチャでは、低バイトは呼び出し毎に変化し、高バイトは0xffffで、これはカーネル仮想アドレス(KASLRでランダム化されたスタックスロットであり固定文字列ではありません)を示しています。RECONF_REQ body (ident=0x02 len=8): 42 fb 54 af 0e ca ff ffRECONF_REQ body (ident=0x02 len=8): 52 3d 2e af 0e ca ff ffRECONF_REQ body (ident=0x02 len=8): b2 fc 5b af 0e ca ff ffこのパッチ適用後は期待通りの6バイトとなり、リトルエンディアンで(mtu, mps, scid)を正しく運搬します。
