CVE-2022-50767

Estado: AplazadaSin puntuar—

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

fbdev: smscufx: Fix several use-after-free bugs

Several types of UAFs can occur when physically removing a USB device.

Adds ufx_ops_destroy() function to .fb_destroy of fb_ops, and in this function, there is kref_put() that finally calls ufx_free().

This fix prevents multiple UAFs.
