Details

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

gpu: lontium-lt9611: Fix NULL pointer dereference in lt9611_connector_init()

A NULL check for bridge->encoder shows that it may be NULL, but it already been dereferenced on all paths leading to the check. 812 if (!bridge->encoder) {

Dereference the pointer bridge->encoder. 810 drm_connector_attach_encoder(&lt9611->connector, bridge->encoder);
