Apple has released critical security updates to address actively exploited zero-day vulnerabilities in its iOS and iPadOS systems, specifically patching CVE-2024-23225 and CVE-2024-23296 to enhance kernel memory protection. The updates, identified as iOS 17.4, aim to fix four vulnerabilities, two of which were being actively exploited, and introduce a new feature called Stolen Device Protection to improve security for iPhone and iPad users. Additionally, the Cybersecurity and Infrastructure Security Agency (CISA) has added these vulnerabilities, along with others affecting Microsoft Windows Kernel and Android Pixel devices, to its Known Exploited Vulnerabilities Catalog. Users are urged to update their devices immediately to protect against potential memory corrupting attacks and to enable the new security feature for added protection against phone theft. The urgency of these updates was highlighted by Apple's earlier minor update, iOS 17.1.1, and the patches were released on March 5.
