CVE-2026-92259 Samsung Opensource CVE debrief

Who should care

Defenders responsible for systems using Samsung Opensource Escargot should assess exposure and verify affected versions, as the vulnerability requires specific access and has a medium impact.

Why it matters

CVE-2026-92259 is a medium-severity vulnerability in Samsung Opensource Escargot that requires write access to the bytecode-cache directory to exploit, potentially leading to denial of service. Defenders should verify affected versions, assess exposure, and monitor official sources for remediation guidance.

• Denial of service via crafted cache file.
• Potential for heap-based buffer overflow.
• Requires verification of affected versions and exposure.
• Remediation priority based on official source guidance.

Technical summary

The vulnerability is caused by an integer overflow or wraparound in Samsung Opensource Escargot, which can lead to a heap-based buffer overflow and denial of service when a crafted cache file is used. This issue affects Escargot version ac94df78493ee6fede286620d94f724e46b4d238. The vulnerability requires write access to the bytecode-cache directory, which limits its exploitability. However, defenders should still prioritize verifying affected versions and assessing exposure due to the medium CVSS score. The technical details are based on the available information and may need to be updated as more information becomes available.

Defensive priority

Defenders should prioritize verifying affected versions and assessing exposure, as the vulnerability requires write access to a specific directory and has a medium CVSS score.

Recommended defensive actions

• Verify if the system uses Samsung Opensource Escargot and assess write access to the bytecode-cache directory.
• Review the GitHub reference for potential patches or mitigations.
• Monitor the CVE and NVD entries for updates on affected versions and remediation.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but its scope and remediation require further verification from official sources. The vulnerability details are based on the information available up to September 15, 2026, and may need to be updated as more information becomes available. Samsung Opensource Escargot's bytecode-cache directory is a critical component that needs to be protected. Defenders should verify the affected versions and assess exposure to this vulnerability.
