CVE-2022-43750: Medium severity Linux Linux kernel vulnerability

Published Sep 22, 2022
·
Updated

An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Other sources

drivers/usb/mon/monbin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory.
