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 0.50% 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 Erlang OTP 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.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 1 structured product or package state 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.

5 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 1 affected package state 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
Stack-based Buffer Overflow vulnerability in Erlang OTP erts (inet_drv) allows an unauthenticated remote attacker to crash the BEAM VM by sending a crafted SCTP ERROR chunk. The sctp_parse_error_chunk function in erts/emulator/drivers/common/inet_drv.c parses SCTP ERROR chunks and writes cause codes into a fixed-size stack-allocated ErlDrvTermData spec[] array without checking bounds. A remote attacker who has established an SCTP association to a listening port can send a single crafted SCTP ERROR chunk containing enough cause codes to overflow the stack buffer, crashing the VM. The attacker can only write 16-bit values interleaved with a fixed tag, so the overflow does not provide a controlled return address, limiting exploitation to Denial of Service. A crafted SCTP ERROR chunk may also leak bits and pieces of Erlang VM memory into the received error packet observed by the Erlang process. Such data is already readable by the user running the Erlang VM, so the disclosure scope is limited. This issue affects OTP from OTP 17.0 before OTP 27.3.4.13, OTP 28.5.0.2, and OTP 29.0.2, corresponding to erts from 6.0 before 15.2.7.9, 16.4.0.2, and 17.0.2. Whether OTP before OTP 17.0, corresponding to erts before 6.0, is affected is unknown.

Summary
A flaw was found in Erlang OTP (Open Telecom Platform) erts, specifically within the `inet_drv` component. An unauthenticated remote attacker can exploit a stack-based buffer overflow vulnerability by sending a specially crafted Stream Control Transmission Protocol (SCTP) ERROR chunk. This can lead to a Denial of Service (DoS) by crashing the BEAM virtual machine. Additionally, this flaw may result in limited information disclosure by leaking small portions of Erlang VM memory.

Why

A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

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.

Erlang OTP の erts (inet_drv) におけるスタックベースのバッファオーバーフローの脆弱性により、認証されていないリモート攻撃者が細工された SCTP ERROR チャンクを送信して BEAM VM をクラッシュさせることが可能です。erts/emulator/drivers/common/inet_drv.c の sctp_parse_error_chunk 関数は SCTP ERROR チャンクを解析し、原因コードを固定サイズのスタック割り当てされた ErlDrvTermData spec[] 配列に境界チェックなしで書き込みます。SCTP 接続を確立したリモート攻撃者は、複数の原因コードを含む細工された単一の SCTP ERROR チャンクを送信してスタックバッファをオーバーフローさせ、VM をクラッシュさせることができます。攻撃者は 16ビット値と固定タグを交互に書き込むことしかできないため、オーバーフローによる制御されたリターンアドレスの書き換えはできず、攻撃はサービス拒否に限定されます。また、細工された SCTP ERROR チャンクにより Erlang VM メモリの断片が Erlang プロセスが受信するエラーパケットに漏洩する場合がありますが、そのデータは Erlang VM を実行するユーザが既に読み取り可能であるため、情報漏洩の範囲は限定的です。この問題は OTP 17.0 から 27.3.4.13、28.5.0.2、29.0.2 の前バージョンおよび erts 6.0 から 15.2.7.9、16.4.0.2、17.0.2 の前バージョンに影響します。
