This vulnerability allows local malicious users to disclose sensitive information 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 handling of IOCTL 0x20006 in the AppleIntelKBLGraphics kext. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel.
