(DoS) It may be in a state. This vulnerability allows local attackers to escalate privileges on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the AppleIntelKBLGraphics kext. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Apple macOS Big Sur is a mobile application APP of Apple (Apple). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2021-07-21-2 macOS Big Sur 11.5 macOS Big Sur 11.5 addresses the following issues.
