fkie_cve-2022-50332

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

video/aperture: Call sysfb_disable() before removing PCI devices

Call sysfb_disable() from aperture_remove_conflicting_pci_devices() before removing PCI devices. Without, simpledrm can still bind to simple-framebuffer devices after the hardware driver has taken over the hardware. Both drivers interfere with each other and results are undefined.

Reported modesetting errors [1] are shown below.
