This flaw allows an attacker to perform out-of-bounds write operations due to insufficient bounds checking. The specific version affected is identified by commit hash 97e8115ab1110bc502b4b5e4a0c689a71520d335. Successful exploitation of this vulnerability could lead to arbitrary code execution, denial of service, or information disclosure. Given the potential impact and the lack of readily available patches, organizations using affected versions of Escargot should take immediate steps to mitigate this risk.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable instance of Samsung Open Source Escargot running commit hash 97e8115ab1110bc502b4b5e4a0c689a71520d335.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious input that triggers the heap-based buffer overflow within Escargot.\u003c/li\u003e\n\u003cli\u003eThe vulnerable function in Escargot attempts to write data beyond the allocated buffer on the heap.\u003c/li\u003e\n\u003cli\u003eThe out-of-bounds write corrupts adjacent memory regions on the heap, potentially overwriting critical data structures or function pointers.\u003c/li\u003e\n\u003cli\u003eThe attacker carefully controls the overwritten data to redirect execution flow to a location of their choosing.\u003c/li\u003e\n\u003cli\u003eThe attacker injects malicious code into the heap and overwrites a function pointer to point to this code.\u003c/li\u003e\n\u003cli\u003eWhen the overwritten function pointer is called, the attacker\u0026rsquo;s code is executed with the privileges of the Escargot process.\u003c/li\u003e\n\u003cli\u003eThe attacker gains control of the system and can perform actions such as installing malware, stealing sensitive data, or disrupting services.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-25205 can lead to a range of negative consequences. An attacker could achieve arbitrary code execution on the affected system, potentially compromising the entire device. This could allow for the installation of persistent backdoors, the theft of sensitive user data, or the complete disruption of service. Given the lack of specific victim data, the impact is assessed as high, especially for systems running Escargot in critical infrastructure or sensitive environments.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReview the pull request at \u003ccode\u003ehttps://github.com/Samsung/escargot/pull/1554\u003c/code\u003e to understand the nature of the vulnerability and potential fixes.\u003c/li\u003e\n\u003cli\u003eImplement input validation and sanitization techniques to prevent malicious input from triggering the buffer overflow.\u003c/li\u003e\n\u003cli\u003eMonitor systems running Samsung Open Source Escargot for unexpected crashes or error messages that may indicate exploitation attempts.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule below to detect potential exploitation attempts based on anomalous process behavior.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-04-13T05:16:02Z","date_published":"2026-04-13T05:16:02Z","id":"/briefs/2026-04-escargot-overflow/","summary":"A heap-based buffer overflow vulnerability in Samsung Open Source Escargot (CVE-2026-25205) allows for out-of-bounds write operations, potentially leading to arbitrary code execution.","title":"Samsung Escargot Heap-Based Buffer Overflow Vulnerability (CVE-2026-25205)","url":"https://feed.craftedsignal.io/briefs/2026-04-escargot-overflow/"}],"language":"en","title":"CraftedSignal Threat Feed — Cve-2026-25205","version":"https://jsonfeed.org/version/1.1"}
