In the Linux kernel, the following vulnerability has been resolved:
drm/gma500/oaktrail_lvds: fix hang on init failure
The LVDS init code looks up an I2C adapter using i2c_get_adapter() and
tries to read the EDID before falling back to allocating and registering
its own adapter.
The error handling does not separate these cases so on a late init
failure it will try to deregister and free also an adapter that had
previously been registered. Since i2c_get_adapter() takes another
reference to the adapter, deregistration hangs indefinitely while
waiting for the reference to be released.
Fix this by only destroying adapters allocated during LVDS init on
errors.
