- Summary
- usb: gadget: u_serial: Add null pointer check in gserial_suspend
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: userial: Add null pointer check in gserialsuspend
Consider a case where gserialdisconnect has already cleared gser->ioport. And if gserialsuspend gets called afterwards, it will lead to accessing of gser->ioport and thus causing null pointer dereference.
Avoid this by adding a null pointer check. Added a static spinlock to prevent gser->ioport from becoming null after the newly added null pointer check.
