The other affects WebKit, the underlying technology of the Safari web browser.įor each of the bugs, the company said it was “aware of a report that this issue may have been actively exploited,” though it provided no further details. The fix for CVE-2022-32893 is now also available for Safari in macOS Big Sur and macOS Catalina.ĬISA has added both CVE's to the list of known to be exploited vulnerabilities with a due date for patching of September 8, 2022.One of the software weaknesses affects the kernel, the deepest layer of the operating system that all the devices have in common, Apple said. And instructions to apply updates are available on the Apple Security Updates page. Users are under advice to implement the updates as soon as possible, by upgrading to:ĭetails can be found on the security content for macOS page. This code could be used to leverage CVE-2022-32894 to obtain kernel privileges Mitigation CVE-2022-32893 could be exploited for initial code to be run. The attack could, for example, be done in the form of a watering hole or as part of an exploit kit. That being said, it seems likely that these vulnerabilities were found in an active attack that chained the two vulnerabilities together. Or when someone is able to reverse engineer the update that fixes the vulnerability. And even then, it depends on the anonymous researcher(s) that reported the vulnerabilities whether we will ever learn the technical details. More detailsĪpple doesn't disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are available. WebKit powers all iOS web browsers and Safari, so possible targets are iPhones, iPads, and Macs which could all be tricked into running unauthorized code.Īpple points out that they are aware of a report that this issue may have been actively exploited. Since the vulnerability exists in Apple’s HTML rendering software (WebKit). An attacker could lure a potential victim to a specially crafted website or use malvertising to compromise a vulnerable system by exploiting this vulnerability. Processing maliciously crafted web content may lead to arbitrary code execution. WebKitĬVE-2022-32893: An out-of-bounds write issue was addressed with improved bounds checking. The kernel privileges are the highest possible privileges, so an attacker could take complete control of a vulnerable system by exploiting this vulnerability.Īpple points out that they are aware of a report that this issue may have been actively exploited. The vulnerability could allow an application to execute arbitrary code with kernel privileges. These are the CVEs you need to know: Kernel privilegesĬVE-2022-32894: An out-of-bounds write issue was addressed with improved bounds checking. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Apple has released emergency security updates to fix two zero-day vulnerabilities previously exploited by attackers to hack iPhones, iPads, or Macs.
