In the Linux kernel, the following vulnerability has been resolved:

usb: fix UAF when probe runs concurrent to dyn ID removal

Dynamic IDs are only guaranteed to be valid when usb_dynids_lock is held,
as remove_id_store can free the node. Thus, make a copy in
usb_probe_interface. Clarify the documentation that the id parameter is
only valid during the probe.

USB serial has the same pattern, but it does not need fixing as the IDs
cannot be removed via sysfs.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2
