A race condition was addressed with additional validation. This issue is fixed in macOS Catalina 10.15.6. A malicious application may be able to execute arbitrary code with kernel privileges.
Se abordó una condición de carrera con una comprobación adicional. Este problema se corrigió en macOS Catalina versión 10.15.6. Una aplicación maliciosa puede ejecutar código arbitrario con privilegios de kernel
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 kernel extension. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel.
