Apple’s iOS 15.4 update has security patches for 39 vulnerabilities
Some iPhone users might have decided not to download and install the update because they don’t wear a mask, or care to use some of the new features including the new emoji. But if you do own an iPhone 6s or newer model, there are some serious security flaws that are addressed in what might be the last major update until iOS 16 arrives.
You need to update your iPhone to iOS 15.4 for security reasons
Several patches were disseminated for the iOS kernel including one to stop malicious apps from elevating privileges. The kernel is the core of an operating system like iOS and controls everything in the system. You might say it is the most important part of any OS and is the go-between that links the hardware to the operating system.
Improve the security of your iPhone and iPad by installing the update ASAP
Another issue with the iOS kernel that is patched in iOS 15.4 could allow a bad actor to perform a denial of service (DoS) attack. A DoS essentially shuts down a device by sending information that causes it to crash, or overloads the device with traffic forcing it to shut down.
