Description OSIDB Bzimport 2025-09-16 17:03:13 UTC 
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.
