Se abordó un problema de corrupción de memoria con una administración de estados mejorada. Este problema es corregido en Security Update 2021-005 Catalina, macOS Big Sur versión 11.6. Un atacante local puede ser capaz de elevar sus privilegios
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 CVMServer daemon. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
