Technically yes and more likely possible if you choose to scan a QR code found on a random web page but you are less likely to be exposed to such malware if you scan a QR to pay vendors or restaurants and typically you will scan the QR code via the money paying app which will tell you that the QR code is a valid address and if not it gives you invalid that is what the security measures inbuilt in those apps.
Well in general, scanning a QR code itself is not a direct way to get malware on your phone but malicious QR codes can redirect you to websites that may attempt to exploit vulnerabilities in your device. So to stay safe, ensure your device's software is up-to-date and be cautious when scanning QR codes from untrusted sources.
Let's say you scan QR of an BEP20 address in your electrum then it will say the address is invalid so there will be no further actions to execute so even if you scan QR code that may lead to a malware website then you are less likely to be affected but if you do with your QR code scanner app then it will become a problem.
