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 0.62% 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. Receiving a DTLS (Datagram Transport Layer Security) record for a future epoch while a handshake is in progress causes OpenSSL to buffer an excessive amount of memory. This allows a peer to cause memory exhaustion, eventually resulting in a denial of service, using a small amount of network traffic.

Summary
Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large amount of memory, which may lead to a Denial of Service. CWE: CWE-405: Asymmetric Resource Consumption (Amplification) Description: While a DTLS handshake is in progress, a peer may legitimately have already moved on to the next epoch (for example, having sent its ChangeCipherSpec and Finished messages) before the local endpoint has processed the same transition, typically because of reordering on the underlying UDP transport. OpenSSL buffers such early records so that they can be processed once the local endpoint catches up. Buffering a record currently retains the entire read buffer it arrived in, which is sized to hold the largest possible DTLS record (around 16 kilobytes), rather than just the bytes that make up the record itself. Up to 100 such records may be buffered per connection. As a result, a peer that sends a stream of small forged records claiming to belong to the next epoch can cause an OpenSSL DTLS endpoint to retain around 1.7 megabytes of memory, despite sending only a small fraction of that amount of data over the network. An attacker therefore gains a memory amplification factor of around 1200, and can multiply the effect across as many associations as it is able to open, making this a remote memory exhaustion Denial of Service risk for DTLS servers. Since the memory retained per connection remains bounded, and any limit an application already places on the number of concurrent associations also bounds the total exposure, this issue has been assessed as Low severity. FIPS impact: no No FIPS modules are affected by this issue as the affected code is outside the OpenSSL FIPS module boundary. OpenSSL 4.0, 3.6, 3.5, 3.4, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue. OpenSSL 4.0 users should upgrade to OpenSSL 4.0.2. OpenSSL 3.6 users should upgrade to OpenSSL 3.6.4. OpenSSL 3.5 users should upgrade to OpenSSL 3.5.8. OpenSSL 3.4 users should upgrade to OpenSSL 3.4.7. OpenSSL 3.0 users should upgrade to OpenSSL 3.0.22.

Why

The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is asymmetric.

How

An attacker operating through a network path 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.

JVN iPedia · Japanese · JVNDB-2026-033265OpenSSL ProjectのOpenSSLにおける非対称のリソース消費に関する脆弱性

問題の概要：ハンドシェイクが進行中に将来のエポックのDTLSレコードを受信すると、OpenSSLはレコード自体が必要とするよりもはるかに多くのメモリをバッファリングしてしまいます。影響の概要：ピアは少量のネットワークトラフィックを使用して、OpenSSLのDTLSエンドポイントに不釣り合いに大きなメモリを保持させることができ、これによりサービス拒否（DoS）攻撃が発生する可能性があります。CWE：CWE-405 非対称リソース消費（増幅）説明：DTLSのハンドシェイクが進行中の間、ピアは正当に次のエポックにすでに進んでいる可能性があります（例えば、ChangeCipherSpecやFinishedメッセージを送信した場合など）。これは通常、基盤となるUDPトランスポートのパケット並べ替えが原因であり、ローカルエンドポイントはまだ同じ遷移を処理していません。OpenSSLはこのような早期のレコードをバッファリングし、ローカルエンドポイントが追いついた際に処理できるようにしています。レコードをバッファリングすると、そのレコードが到着した読み取りバッファ全体（最大のDTLSレコードサイズである約16キロバイトに設定されています）が保持され、レコード自体のバイト数だけではありません。接続ごとに最大で100個のレコードがバッファリングされる可能性があります。その結果、次のエポックに属すると偽装した小さな偽造レコードのストリームを送信するピアは、ネットワーク上で実際に送信したデータ量のわずかな部分しか使っていないにもかかわらず、OpenSSLのDTLSエンドポイントに約1.7メガバイトのメモリを保持させることが可能です。攻撃者はこのため約1200倍のメモリアンプルフィケーション効果を得られ、開くことができる多くの関連付けに対してこの効果を増幅させることもできます。これにより、DTLSサーバーに対するリモートメモリ枯渇型のサービス拒否リスクが発生します。接続ごとに保持されるメモリは上限があり、またアプリケーションが既に設けている同時関連付け数の制限も総露出量を制限するため、本問題の深刻度は低いと評価されています。FIPSへの影響：なし影響を受けるコードはOpenSSLのFIPSモジュールの境界外にあるため、本問題によるFIPSモジュールへの影響はありません。OpenSSLのバージョン4.0、3.6、3.5、3.4、3.0、1.1.1および1.0.2が本問題の影響を受けます。OpenSSL 4.0ユーザーにはOpenSSL 4.0.2へのアップグレードを推奨します。OpenSSL 3.6ユーザーにはOpenSSL 3.6.4へのアップグレードを推奨します。OpenSSL 3.5ユーザーにはOpenSSL 3.5.8へのアップグレードを推奨します。OpenSSL 3.4ユーザーにはOpenSSL 3.4.7へのアップグレードを推奨します。OpenSSL 3.0ユーザーにはOpenSSL 3.0.22へのアップグレードを推奨します。プレミアムサポート契約者のみ：OpenSSL 1.1.1ユーザーにはOpenSSL 1.1.1ziへのアップグレードを推奨します。OpenSSL 1.0.2ユーザーにはOpenSSL 1.0.2zrへのアップグレードを推奨します。本問題は2026年5月18日にAmazon Web Servicesによって報告されました。修正はMatt Caswellによって開発されました。-- 切り取り（公開されない社内用メタデータ）--報告者：Amazon Web Services 修正者：Matt Caswell
