Apple Has Patched An Actively Exploited Zero-day Vulnerability In iOS And iPadOS

On Monday, Apple released new updates to address a zero-day vulnerability in iOS and iPadOS devices, which has reportedly been actively exploited in the wild. The kernel’s out-of-bounds write vulnerability (CVE-2022-42827) could be exploited by malicious applications to execute arbitrary code with administrative privileges. “Apple is aware of a report that this issue may have been actively exploited,” the company said in a statement. “Improved bounds checking was used to address an out-of-bounds write issue.” The update is available for the iPhone 8 and later, the iPad Pro (all models), the iPad 5th generation and later, the iPad Air 3rd generation and later, and the iPad mini 5th generation and later. The vulnerability was discovered by an unidentified researcher. The patched vulnerability is the third of its kind that Apple has patched in the last few months, following CVE-2022-32894 and CVE-2022-32917, both of which were reportedly exploited in the wild. In addition to CVE-2022-42827, Apple’s latest update fixes 19 other security flaws. CVE-2022-42813, CVE-2022-42808, CVE-2022-42823, and CVE-2022-32922 are all vulnerabilities that could lead to arbitrary code execution. The company’s changelog page for the iOS 16.1 update contains a complete list of the vulnerabilities fixed this week in iOS 16.1, including those affecting AppleMobileFileIntegrity, AVEVideoEncoder, Core Bluetooth, GPU Drivers, IOHIDFamily, Sandbox, and Shortcuts. In general, this year has seen at least eight documented in-the-wild zero-day attacks against Apple devices running macOS, iOS, and iPadOS. In each of these cases, Apple did not provide details on the active exploitation or indicators of compromise (IoC) or other data to assist iOS users in looking for signs of infection. The iOS 16.1 update arrives just weeks after Fast Company’s Apple News account was hacked and obscene push notifications were sent to users’ mobile devices. Apple News then removed the account, and it has not been reinstated as of this writing.
