Description OSIDB Bzimport 2024-09-27 13:23:19 UTC

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

usbnet: ipheth: do not stop RX on failing RX callback

RX callbacks can fail for multiple reasons:

* Payload too short
* Payload formatted incorrecly (e.g. bad NCM framing)
* Lack of memory

None of these should cause the driver to seize up.

Make such failures non-critical and continue processing further
incoming URBs.
