Summary
In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: analogix_dp: fix unchecked bound endpoint name length rockchip_dp_drm_encoder_enable() uses sprintf() to format a device tree path into a 32-byte stack buffer. Device tree paths are not limited to this size, so a sufficiently long path can overflow the buffer. Use snprintf() with the destination size to truncate the generated name and keep the writes within bounds.
