The vulnerabilities listed[0] look pretty severe. I've got a 2016 iPhoneSE running iOS 15. It receives the odd security update (last one was on September 15 this year), but I imagine if these vulnerabilities aren't backported it would be pretty insecure. Currently my bank still supports iOS 15 but I wonder for how much longer? [0] https://support.apple.com/en-us/125885 https://support.apple.com/en-us/125885
