kernel: sfc: fix crash when reading stats while NIC is resetting

A flaw was identified in the sfc network driver within the Linux kernel where a NULL pointer dereference may occur when reading network statistics during a NIC reset. Specifically, the function efxnetstats used as .ndogetstats64 for ethtool can be invoked while the NIC’s internal data structures...

SUSE CVE-2022-48647

In the Linux kernel, the following vulnerability has been resolved: sfc: fix TX channel offset when using legacy interrupts In legacy interrupt mode the txchanneloffset was hardcoded to 1, but that's not correct if efxsepparatetxchannels is false. In that case, the offset is 0 because the tx queu...
