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 1.54% 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 OpenSSL OpenSSL 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.

Summary
A flaw was found in OpenSSL. A malformed INITIAL packet with an invalid DCID (destination connection ID) can cause the QUIC server to double free the QRX object. This issue leads to memory corruption, causing the termination of the QUIC server process and resulting in a denial of service.

Issue summary: QUIC server may double free QRX (QUIC record layer RX) object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence that this double free is exploitable for remote code execution, thus it is considered highly improbable. CWE: CWE-415: Double Free Description: In order to validate initial packet, OpenSSL QUIC stack default packet handler (port_default_packet_handler()) creates a so-called QRX object. If the initial packet validates successfully with QRX object, the default packet handler proceeds to channel (connection object) creation. The QRX object used for packet validation is passed to port_bind_channel(), so it becomes part of the newly created connection. If port_bind_channel() fails, then it also frees the QRX object. Once port_bind_channel() returns, the port_default_packet_handler() detects the failure and proceeds to the error branch, where the same QRX object is freed for the second time. The failure in port_bind_channel() function can be induced with a relatively low effort by a malformed (non RFC 9000 compliant) INITIAL packet. If the packet carries DCID (destination connection ID) which is shorter than 8 bytes, then port_bind_channel() jumps to the error path after ossl_quic_lcidm_enrol_odcid() detects that the DCID has invalid length. FIPS impact: no The FIPS module is not affected, as the QUIC implementation is outside of the OpenSSL FIPS module boundary.

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-2026-035407OpenSSL ProjectのOpenSSLにおける二重解放に関する脆弱性

問題の概要：QUICサーバは初期パケットのチャネル作成が失敗した際に、QRX（QUICレコード層RX）オブジェクトを二重に解放する可能性があります。影響の概要：二重解放はヒープ破損を引き起こし、通常はQUICサーバプロセスを終了させ、サービス拒否（DoS）状態を招きます。現時点で、この二重解放がリモートコード実行に悪用可能である証拠はなく、その可能性は非常に低いと考えられています。CWE：CWE-415：二重解放。説明：初期パケットの検証のために、OpenSSLのQUICスタックのデフォルトパケットハンドラ（port_default_packet_handler()）は、いわゆるQRXオブジェクトを作成します。初期パケットがQRXオブジェクトで正常に検証されると、デフォルトパケットハンドラはチャネル（接続オブジェクト）の作成に進みます。パケット検証に使用されたQRXオブジェクトはport_bind_channel()に渡され、新しく作成された接続の一部となります。port_bind_channel()が失敗すると、QRXオブジェクトも解放されます。port_bind_channel()の戻り後、port_default_packet_handler()は失敗を検知してエラーブランチに進み、同じQRXオブジェクトを二度目に解放してしまいます。port_bind_channel()関数の失敗は、比較的低い労力で不正（RFC 9000非準拠）のINITIALパケットによって引き起こすことができます。パケットが8バイト未満のDCID（宛先接続ID）を含む場合、ossl_quic_lcidm_enrol_odcid()がDCIDの無効な長さを検出し、その後port_bind_channel()はエラーパスにジャンプします。FIPSへの影響：なし。FIPSモジュール境界外の実装であるため、QUICの実装はOpenSSLのFIPSモジュールに影響を与えません。
