CVE-2022-27950 concerns a reported resource-retention condition in the Linux kernel HID ELO driver on kernels prior to 5.16.11. A specific HID parsing error path could retain a reference to the associated USB device. Upstream maintainers subsequently concluded that both the change introducing the behavior and the initial purported fix were incorrect and reverted them. The issue was disputed as a conventional memory leak because the retained USB-device reference was not usable outside the module scope, but it could cause problems when the device was disconnected.
