JSON

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a
race condition and resultant use-after-free if a physically proximate
attacker removes a USB device while calling open(), aka a race condition
between ufx_ops_open and ufx_usb_disconnect.

Notes

Author	Note
sbeattie	requires removing the USB device which usually requires physical proximity, therefore marking the priority of this issue as low.
