Device crash via malformed camera test message
Published Sep 14, 2026 · Updated Sep 14, 2026
Out-of-bounds write in the camera component of Samsung Exynos 1330 firmware through 2025-12-02 allows attackers to crash the device. The camera driver accepts a malformed message through the test_msg sysfs entry and writes beyond the destination buffer. Reaching the condition requires access to that device-local sysfs entry; the reported consequence is a denial-of-service crash, not code execution or data disclosure.
