Apple Delivers Urgent Security Patches

Critical CoreMedia Bug

Apple has released new software updates to fix several security problems found across its products. One of these flaws, called CVE-2025-24085, is a zero-day bug in the CoreMedia feature. This bug allows an already-installed malicious app on a device to gain higher-level access than it should.

According to Apple, there is evidence that older iOS versions (before iOS 17.2) might have been attacked using this flaw. The company has addressed the problem by improving how memory is handled on various devices and operating systems:

  • iOS 18.3 and iPadOS 18.3 – For iPhone XS and newer, several iPad Pro models, iPad Air (3rd gen and newer), iPad (7th gen and newer), and iPad mini (5th gen and newer)
  • macOS Sequoia 15.3 – For Macs running macOS Sequoia
  • tvOS 18.3 – For Apple TV HD and Apple TV 4K (all versions)
  • visionOS 2.3 – For Apple Vision Pro
  • watchOS 11.3 – For Apple Watch Series 6 and newer

So far, Apple has not shared details on exactly how this zero-day was used, who was behind it, or which targets were affected.

AirPlay and CoreAudio Fixes

The new updates also tackle five security issues in AirPlay, all discovered by Uri Katz from Oligo Security. In certain situations, these flaws could lead to unexpected system crashes, denial-of-service attacks, or malicious code being run on the device.

Additionally, Google’s Threat Analysis Group (TAG) found and reported three problems in the CoreAudio component—labeled as CVE-2025-24160, CVE-2025-24161, and CVE-2025-24163. These could cause an app to close without warning when it tries to play a specially crafted audio file.
