| Vector | AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:L |
Name of the Vulnerable Software and Affected Versions
QEMU version 5.0.0
Description
The issue is related to a buffer over-read in the QEMU hardware emulation, specifically in the
hw/usb/hcd-ohci.c file. This can allow an attacker to access confidential data, compromise data integrity, and cause a denial of service. The vulnerability is caused by a stack-based buffer over-read via values obtained from the host controller driver.Recommendations
For QEMU version 5.0.0, consider disabling the
hw/usb/hcd-ohci.c module to minimize the risk of exploitation until a patch is available. Restrict access to the vulnerable hcd-ohci controller to prevent potential attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
