Apple on Wednesday released security updates for iOS, iPadOS, and macOS platforms to remediate two zero-day vulnerabilities previously exploited by threat actors to compromise its devices.
The list of issues is below -
- CVE-2022-32893 - An out-of-bounds write issue in WebKit which could lead to the execution of arbitrary code by processing a specially crafted web content
- CVE-2022-32894 - An out-of-bounds write issue in the operating system's Kernel that could be abused by a malicious application to execute arbitrary code with the highest privileges
Apple said it addressed both the issues with improved bounds checking, adding it's aware the vulnerabilities "may have been actively exploited."
The company did not disclose any additional information regarding these attacks or the identities of the threat actors perpetrating them, although it's likely that they were abused as part of highly-targeted intrusions.
