Summary
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.
