Title
usb: renesas_usbhs: Flush the notify_hotplug_work
Summary
In the Linux kernel, the following vulnerability has been resolved: usb: renesas_usbhs: Flush the notify_hotplug_work When performing continuous unbind/bind operations on the USB drivers available on the Renesas RZ/G2L SoC, a kernel crash with the message "Unable to handle kernel NULL pointer dereference at virtual address" may occur. This issue points to the usbhsc_notify_hotplug() function. Flush the delayed work to avoid its execution when driver resources are unavailable.
