LIN1021-6782 : Security Advisory - qemu - CVE-2023-5088

Created: Nov 1, 2023 Updated: Nov 8, 2023

Found In Version: 10.21.20.1

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: Userspace

Description

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
