The full text of the report can be found here . The researchers described the ways in which they managed to bypass protection on Samsung devices. Most of the information is obscure to ordinary users who are not information security specialists. However, experts report that in most cases they should not be concerned.
All of the issues mentioned are known to have been fixed by Samsung , which was made aware of the vulnerability shortly after it was discovered. The first patch was released in August 2021, and the vulnerability was finally fixed with a security patch in October.
