Description (CNA)
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.
