An urgent security alert has been issued for Android users, warning of a critical flaw that could potentially allow cyber attackers to bypass the lock screen on certain devices. The security vulnerability, labeled as CVE-2026-20435, impacts Android devices utilizing MediaTek processors, which are commonly found in budget-friendly smartphones.
Security researchers demonstrated how the exploit works by connecting a susceptible phone to a laptop via USB and successfully retrieving the device’s PIN, decrypting storage, and accessing sensitive data within a minute. This flaw enables attackers to extract encryption keys before the system fully boots, circumventing security measures like full-disk encryption and lock screen protection.
To mitigate the risk posed by this vulnerability, users are advised to check their device’s processor information in the Settings menu and ensure that any available security updates are promptly installed, especially if their phone runs on a MediaTek chip. MediaTek has already released a patch for the issue, but users should wait for individual device manufacturers to distribute the fix through software updates.
It is crucial to note that this attack requires physical access to the device, making the risk significantly lower if the phone is kept secure and regularly updated. However, older devices that no longer receive updates may remain vulnerable, prompting users with such devices to exercise caution or consider upgrading to newer models for enhanced security.
