My understanding is that your model gets security patches on quarterly basis. So since 2nd quarter has just got over, the update must be rolled out soon. You can also check to see if there’s an update available yourself by opening the Settings app on your device, navigating to Software Update, then tapping the download option (this can be Download updates manually or Download and install depending on your OS version). On older devices, the Software update menu may be inside the About device section of the Settings app. Link for previous update for your reference https://samnext.com/samsung-galaxy-m42-5g-april-2021-security-patch/
