The first issue (CVE-2022-22674) only affects Macs, and a lot more particularly the Intel Graphics Driver. Apple said the vulnerability included an out-of-bounds go through issue that could lead to the disclosure of kernel memory.
Apple thinks the issue might have been exploited by hackers in the previous and has fastened it by improving enter validation, it said in an advisory.
Out-of-bounds examine flaws generally make it possible for attackers to browse sensitive information and facts from other memory spots, or bring about a crash on the system.
The next vulnerability (CVE-2022-22675) impacts iPhones, iPads, and Macs. A flaw in AppleAVD, an audio/video decoding framework employed by Apple equipment, allowed for arbitrary code to be executed with kernel privileges. The vulnerability, also believed to have been exploited in the earlier, was induced by an out-of-bounds generate issue that Apple fixed by bettering bounds examining.
Identical to out-of-bounds read issues, out-of-bounds compose flaws manifest when software modifies an index or performs pointer arithmetic that references a memory locale outdoors of the buffer’s boundaries. This can direct to data corruption, a gadget crash, or, in this situation, code execution.
Apple has launched crisis patches for all impacted devices on iOS (15.4.1), iPadOS (15.4.1), and macOS (12.3.1). These include iPhone 6 products and more recent, all iPad Pro styles, iPad Air 2 and newer, iPad 5th generation and more recent, iPad mini4 and more recent, and iPod Contact 7th generation.
Importantly, the security patch for Macs appears to be to only be offered on macOS Monterey, which suggests equipment will need to be up to date to the latest edition of the working method.
Security fixes for Apple Television set (tvOS 15.4.1) and Apple Check out (watchOS 8.5.1) had been also unveiled in new updates, but Apple has not nonetheless provided any info for these or assigned CVE tracking codes.
A 12 months entire of zero-days
The most recent round of emergency patches from Apple addresses the fourth and fifth zero-day vulnerabilities impacting units in the company’s product ecosystem this yr.
An array of security issues, including two zero-times, were patched in January that all associated code execution flaws, some with kernel privileges far too, related to CVE-2022-22675.
Close to two months afterwards, Apple was forced to issue yet another unexpected emergency patch for a critical WebKit flaw. WebKit is the engine that powers the Safari browser and the code execution flaw also had evidence of earlier active exploitation.
