The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to a boundary condition within the prl_hypervisor kext. A local user to run a specially crafted program to trigger out-of-bounds read error and execute arbitrary code in the context of the hypervisor.


4) Out-of-bounds write (CVE-ID: CVE-2020-17399)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when processing untrusted input within the prl_hypervisor kext. A local user can run a specially crafted program to trigger out-of-bounds write and execute arbitrary code in the context of the kernel.


5) Out-of-bounds read (CVE-ID: CVE-2020-17398)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the prl_hypervisor kext. A local user can run a specially crafted program to trigger out-of-bounds read error and read contents of memory on the system.


6) Out-of-bounds read (CVE-ID: CVE-2020-17397)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary condition within the handling of network packets. A local user can run a specially crafted application to trigger out-of-bounds read error and  in the context of the hypervisor.


7) Integer overflow (CVE-ID: CVE-2020-17396)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow within the prl_hypervisor module. A local user can run a specially crafted program to trigger integer overflow and execute arbitrary code in the context of the kernel.


8) Integer underflow (CVE-ID: CVE-2020-17395)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
