NVD

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

can: usb: etas es58x: correctly anchor the urb in the read bulk callback

When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usb kill anchored urbs() is called. This logic is correctly done elsewhere in the driver, except in the read bulk callback so do that here also.
