The iPhone maker said it addressed CVE-2024-44308 and CVE-2024-44309 with improved checks and improved state management, respectively.

Not much is known about the exact nature of the exploitation, but Apple has acknowledged that the pair of vulnerabilities “may have been actively exploited on Intel-based Mac systems.”

Clément Lecigne and Benoît Sevens of Google’s Threat Analysis Group (TAG) have been credited with discovering and reporting the two flaws, indicating that they were likely put to use as part of highly-targeted government-backed or mercenary spyware attacks.

The updates are available for the following devices and operating systems –

• iOS 18.1.1 and iPadOS 18.1.1 – iPhone XS and later, iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later

• macOS Sequoia 15.1.1 – Macs running macOS Sequoia
• visionOS 2.1.1 – Apple Vision Pro

Apple has so far addressed a total of four zero-days in its software this year, including one (CVE-2024-27834) that was demonstrated at the Pwn2Own Vancouver hacking competition. The other three were patched in January and March 2024.

Users are advised to update their devices to the latest version as soon as possible to safeguard against potential threats.
