No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A weakness has been identified in embedded-graphics up to 0.8.2 on 32-bit. Impacted is the function ImageRaw::new/bytes_per_row of the file src/image/image_raw.rs. This manipulation causes integer overflow. The attack is possible to be carried out remotely. Upgrading the affected component is recommended. The project was informed of the problem early through an issue report but has not responded yet.
