The updates, which arrive much less than a week immediately after the firm launched iOS 14.7, iPadOS 14.7, and macOS Large Sur 11.5 to the community, fixes a memory corruption issue (CVE-2021-30807) in the IOMobileFrameBuffer ingredient, a kernel extension for managing the screen framebuffer, that could be abused to execute arbitrary code with kernel privileges.
The business stated it addressed the issue with improved memory managing, noting it is “knowledgeable of a report that this issue may perhaps have been actively exploited.” As is generally the case, additional information about the flaw have not been disclosed to reduce the weaponization of the vulnerability for additional attacks. Apple credited an nameless researcher for getting and reporting the vulnerability.

CVE-2021-30807 is also the thirteenth zero-working day vulnerability addressed by Apple this calendar year by yourself, such as —
- CVE-2021-1782 (Kernel) – A destructive software might be equipped to elevate privileges
- CVE-2021-1870 (WebKit) – A distant attacker could be able to result in arbitrary code execution
- CVE-2021-1871 (WebKit) – A distant attacker may possibly be ready to result in arbitrary code execution

- CVE-2021-30762 (WebKit) – Processing maliciously crafted web articles may perhaps direct to arbitrary code execution
Presented the general public availability of a proof-of-principle (PoC) exploit, it is really hugely encouraged that consumers transfer promptly to update their units to the hottest model to mitigate the risk associated with the flaw.
