Hackers Exploiting iOS 0-Day To Attack iPhones

Apple releases emergency fixes to address two new zero-day vulnerabilities in iOS that impact iPhones.

The two zero-day vulnerabilities were discovered in RTKit, tracked as CVE-2024-23296, and the iOS Kernel, tracked as CVE-2024-23225.

If exploited by an attacker with kernel read and write privileges, this zero-day might also be used to bypass kernel memory protections.

“Apple is aware of a report that this issue may have been exploited,” Apple said in its advisory.

Details Of The Two-Zero Days Exploited Vulnerabilities

Kernel CVE-2024-23225

An issue with memory corruption has been fixed by improved validation.

“An attacker with arbitrary kernel read and write capability may be able to bypass kernel memory protections,” the company said.

Impacted Devices:

iPhone XS and later, iPad Pro 12.9-inch 2nd generation and later, iPad Pro 10.5-inch, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 6th generation and later, and iPad mini 5th generation and later.

RTKit -CVE-2024-23296

Enhanced validation fixed an issue with memory corruption. However, if an attacker has arbitrary kernel read and write access, it might be possible to bypass kernel memory protections.

Apple has not stated if the two zero-days were found internally or who reported them.

Impacted Devices:

iPhone XS and later, iPad Pro 12.9-inch 2nd generation and later, iPad Pro 10.5-inch, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 6th generation and later, and iPad mini 5th generation and later.

Fixes Available

Apple fixed the security vulnerabilities for iPad 16.7.6, iOS 17.4, iPadOS 17.4, iOS 16.76, and iOS 17.4.

Other Security Flaws Addressed

Apple fixed a privacy vulnerability in the Accessibility feature (CVE-2024-23243) that would have let apps access sensitive location data.

Also, when Locked Private Browsing is enabled, a Safari Private Browsing flaw tracked as CVE-2024-23256 exposes users’ locked tabs while they move tab groups.

The business stated that more patches that have not yet been described will be published to the advisory later along with CVEs detailing additional issues. 

Because hackers are already using these two flaws in their attacks, ensure that you apply the relevant security upgrades as soon as possible if you own a vulnerable iPhone, iPad, or Mac.
