Given that all three of these vulnerabilities are known to have been exploited already, it is imperative that users update to the patched versions of iOS, iPadOS as soon as possible. The latter vulnerability is within WebKit, and the act of processing content could lead to arbitrary code execution.ĬVE-2023-41991 and CVE-2023-41992 also impact Apple Watch users, and an emergency security update to watchOS 10.0.1 is also now available. The first of these involves a certificate validation issue, and successful exploitation can enable an attacker to bypass such validation using a malicious app. The same two security researchers are also credited with disclosing both CVE-2023-41991 and CVE-2023-41993. This is a kernel vulnerability that could enable an attacker to elevate privileges.

If you are getting your new iPhone 15, iPhone 15 Plus, iPhone 15 Pro or iPhone 15 Pro Max at launch, you will need to update the operating system immediately. The security update addresses three critical vulnerabilities, and Apple warns that it is aware of reports that the trio may have been actively exploited against versions of the iPhone operating system before iOS 16.7. This emergency iPhone update, and one which all iPhone and iPad users should apply as soon as possible, comes with a critical warning. “We strongly encourage all Apple users that may be at risk because of who they are or what they do to enable Lockdown Mode,” Railton says.Īpple has released iOS 17.0.1 and iPadOS 17.0.1, just days after the latest operating system was launched with much fanfare. Railton says that using Lockdown Mode would have prevented the attack from being successful, something Apple’s Security Engineering & Architecture Team has confirmed.
