CVE-2026-23788: CWE-122 Heap-based Buffer Overflow in Samsung Exynos 1280 firmware
CVE-2026-23788 is a heap-based buffer overflow vulnerability in the Exynos DRM HDR driver affecting Samsung Mobile Processor Exynos 1280, 2200, and 1380. The flaw arises from improper buffer size validation in the Display Processing Unit (DPU), leading to kernel memory corruption and potential system crashes. The vulnerability has a medium severity rating with a CVSS score of 4.2. No known exploits are reported in the wild, and no official patch information is provided.
AI Analysis
Technical Summary
This vulnerability involves a heap overflow in the Exynos DRM HDR driver within Samsung Mobile Processor Exynos 1280, 2200, and 1380 firmware. The root cause is improper validation of buffer sizes in the Display Processing Unit, which can cause kernel memory corruption and result in system crashes. The CVSS 3.1 base score is 4.2, reflecting low attack vector (local), high attack complexity, low privileges required, no user interaction, scope changed, no confidentiality impact, low integrity impact, and low availability impact.
Potential Impact
Successful exploitation can lead to kernel memory corruption and system crashes, potentially causing denial of service. There is no indication of confidentiality compromise, but integrity and availability impacts are low and limited to system stability issues. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, limiting local access and monitoring for abnormal system crashes may reduce risk.
