CVE-2023-21264

Published: 14 August 2023

In multiple functions of mem_protect.c, there is a possible way to access hypervisor memory due to a memory access check in the wrong place. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

From the Ubuntu Security Team

It was discovered that the ARM64 KVM implementation in the Linux kernel did not properly restrict hypervisor memory access. An attacker in a guest VM could use this to execute arbitrary code in the host OS.

Notes

Author	Note
	Priority reason: Local guest-to-host data theft and potential privilege escalation.
