VAR-202104-0160
Vulnerability from variot - Updated: 2026-03-09 22:30An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave, macOS Big Sur 11.0.1. An application may be able to execute arbitrary code with kernel privileges. 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 handling of IOCTL 0x10008 in 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. Apple macOS is a set of dedicated operating systems developed by Apple Corporation for Mac computers. Apple macOS security vulnerability, currently there is no information about this vulnerability, please keep an eye on CNNVD or manufacturer announcements
