SAP has released an emergency security patch to address a maximum-severity memory corruption flaw in its core kernel, tracked as CVE-2026-5100. The vulnerability, dubbed "OVERPASS," carries a critical CVSS score of 10.0, and immediate remediation is required to prevent a complete system compromise.
The flaw resides within the SAP Kernel, the trusted, low-level computing base that underpins the entire platform. Successful exploitation of OVERPASS could grant an attacker full control over the affected system. This issue is exceptionally widespread because the vulnerable kernel component is integral to major SAP products, including the SAP NetWeaver Application Server and the S/4HANA ERP suite.
This critical update is part of SAP's broader September 2026 security release, which patches a total of 20 vulnerabilities across its product portfolio. The comprehensive update includes fixes for several high-severity issues, highlighting SAP's extensive response to identified risks.
For enterprise IT security teams, particularly those in finance, manufacturing, and logistics, the directive is unequivocal. The OVERPASS vulnerability constitutes a severe and immediate threat. Organizations must inventory their SAP landscapes, test the provided security notes, and deploy the patch with the highest priority to mitigate the risk of a full platform takeover.
This incident underscores the severe consequences of flaws within foundational software layers. The location of OVERPASS within the kernel means it bypasses higher-level application security controls, making rigorous and timely patch management for core systems a non-negotiable operational imperative. Security teams should treat this patch as critical and verify deployment across all mission-critical SAP installations without delay.
SAP 已發布緊急安全補丁，以修補其核心內核中一個被追蹤為 CVE-2026-5100 的嚴重程度最高的記憶體損壞漏洞。該漏洞被稱為「OVERPASS」，其 CVSS 評分為關鍵性的 10.0 分，必須立即進行補救以防止系統被完全攻陷。
該漏洞存在於 SAP 內核之中。SAP 內核是一個可信賴的低階運算基礎，支撐著整個平台。成功利用 OVERPASS 漏洞可能賦予攻擊者對受影響系統的完全控制權。此問題範圍極其廣泛，因為存在漏洞的內核元件是 SAP 主要產品的核心組件，包括 SAP NetWeaver 應用伺服器和 S/4HANA ERP 套件。
這項關鍵更新是 SAP 2026 年 9 月更廣泛安全發布的一部分，該發布針對其產品組合中的漏洞共修補了 20 個。這項全面更新包含了針對多個高嚴重性問題的修補，突顯了 SAP 對已識別風險的廣泛應對。
對於企業 IT 安全團隊，尤其是金融、製造和物流行業的團隊而言，指令是明確的。OVERPASS 漏洞構成嚴重且迫在眉睫的威脅。組織必須清點其 SAP 環境，測試提供的安全說明，並以最高優先級部署補丁，以降低平台被完全接管的風險。
此事件突顯了基礎軟體層級漏洞的嚴重後果。OVERPASS 漏洞位於內核之中，意味著它繞過了高階應用程式安全控制，這使得對核心系統進行嚴格且及時的補丁管理成為一項不可商量的運作要求。安全團隊應將此補丁視為關鍵，並毫不延遲地驗證所有關鍵 SAP 安裝的部署情況。
