Deskripsi (NVD)

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.3-47255. 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 handler for HOST_IOCTL_SET_KERNEL_SYMBOLS in the prl_hypervisor kext. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-10519.
