CVE-2022-1651

Published: 12 May 2022

A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to leak unauthorized kernel information, causing a denial of service.
