It would be interesting to know how many of the fixed vulnerabilities actually pose a real, easily-exploitable threat to phone users in normal use. In my experience, the risks created by vast majority of these ‘vulnerabilities’ are largely not-exploitable ‘in real life’. It is the so-called ‘0 day vulnerabilities’ that can pose a real threat - and that Murena promise to provide prompt fixes for - and the linked article does not identify any of the fixed vulnerabilities being ‘0 day’. So probably not worth worrying about for a normal phone user.
