Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel's USB gadget u serial driver. Specifically, a null pointer dereference can occur in the gserial resume() function if gserial disconnect() has already cleared gser->ioport and a wakeup interrupt triggers the function. A static spinlock was added to prevent gser->ioport from becoming null after the check.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
