- Summary
- usb: ucsi: Fix NULL pointer deref in ucsi_connector_change()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: ucsi: Fix NULL pointer deref in ucsiconnectorchange()
When ucsiinit() fails, ucsi->connector is NULL, yet in case of ucsiacpi we may still get events which cause the ucsacpi code to call ucsiconnector_change(), which then derefs the NULL ucsi->connector pointer.
Fix this by not setting ucsi->ntfy inside ucsiinit() until ucsiinit() has succeeded, so that ucsiconnectorchange() ignores the events because UCSIENABLENTFYCONNECTORCHANGE is not set in the ntfy mask.
