Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005747 advisory.

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

 fbdev/ep93xx-fb: Do not assign to struct fb_info.dev

 Do not assing the Linux device to struct fb_info.dev. The call to register_framebuffer() initializes the field to the fbdev device.
 Drivers should not override its value.

 Fixes a bug where the driver incorrectly decreases the hardware device's reference counter and leaks the fbdev device.

 v2:
 * add Fixes tag (Dan)
