CVE-2026-20486 · Severity: medium · CVSS 6.7 · Published 2026-08-03

MediaTek's imgsensor component handles camera image processing on mobile chipsets. A flaw in its error handling can cause the application to crash unexpectedly. While the crash itself may seem benign, an attacker who already has System-level privileges could exploit this to escalate or maintain their access to the device.
