Cybersecurity researcher David Schütz accidentally found a way to bypass the lock screen on his fully patched Google Pixel 6 and Pixel 5 smartphones, enabling anyone with physical access to the device to unlock it.Exploiting the vulnerability to bypass the lock screen on Android phones is a simple five-step process that wouldn't take more than a few minutes.Schütz says he discovered the flaw by accident after his Pixel 6 ran out of battery, entered his PIN wrong three times, and recovered the locked SIM card using the PUK (Personal Unblocking Key) code.This caused not only the PUK security screen to be dismissed but also the next security screen in the stack, which is the keyguard, followed by whatever screen was next queued in the stack.Schütz reported the flaw to Google in June 2022, and although the tech giant acknowledged the reception and assigned a CVE ID of CVE-2022-20465, they didn’t release a fix until November 7, 2022."
