Vulnerability from github – Published: 2026-09-25 12:31 – Updated: 2026-09-25 12:31

Details

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.
