CVE-2026-33956: CWE-787 Out-of-bounds Write in Samsung Exynos 1330 firmware
CVE-2026-33956 is a low-severity vulnerability in Samsung Exynos mobile processor firmware affecting several models including Exynos 1330, 1380, 1480, 2400, 1580, and 2500. The flaw involves an out-of-bounds write triggered by sending a malformed message to the test_msg sysfs entry in the camera component, which can cause a denial of service. No known exploits are reported, and the vulnerability requires local access with low privileges and high attack complexity. The impact is limited to availability disruption without confidentiality or integrity compromise.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-33956) is an out-of-bounds write (CWE-787) in the camera subsystem of Samsung Exynos mobile processors (models 1330, 1380, 1480, 2400, 1580, and 2500). It is triggered by sending a malformed message to the test_msg sysfs entry, leading to denial of service. The CVSS 3.1 base score is 2.8, reflecting low severity due to local attack vector, high attack complexity, and limited impact (availability only).
Potential Impact
Successful exploitation causes a denial of service by triggering an out-of-bounds write in the camera firmware, potentially crashing or destabilizing the affected device. There is no impact on confidentiality or integrity. Exploitation requires local access with low privileges and has high complexity, limiting the risk.
Mitigation Recommendations
No official patch or remediation information is currently available. Patch status is not yet confirmed — check Samsung's vendor advisory for current remediation guidance. Until a fix is released, restrict local access to the device and avoid interacting with the test_msg sysfs entry in the camera subsystem.
