Technical description

In the Linux kernel, the following vulnerability has been resolved:

phy: ti: phy-omap-usb2: Fix NULL pointer dereference for SRP

If the external phy working together with phy-omap-usb2 does not implement

send_srp(), we may still attempt to call it. This can happen on an idle

Ethernet gadget triggering a wakeup for example:

configfs-gadget.g1 gadget.0: ECM Suspend

configfs-gadget.g1 gadget.0: Port suspended. Triggering wakeup
