Description Rohit Keshri 2023-01-18 19:19:48 UTC 
A race condition may occur if the user physically removes the pcmcia device while calling open() for this char device node. This is a race condition between the scr24x_open() function and the scr24x_remove() function, which may eventually result in UAF.
