The New iOS 15.4.1 Update Will Also Fix Critical Security Vulnerability
Moreover, the update also addresses a problem related to ‘Made for iPhone’ and ‘Made for iPad’ hearing devices that were becoming unresponsive to some third-party apps. The latest new iOS update also fixes a security bug within the AppleAVD media decoder that would allow an attacker to execute arbitrary code with kernel privileges.
