CVE-2026-53279

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