In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum: Protect driver from buggy firmware
When processing port up/down events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not the CPU port (local port 0), which exists, but lacks a netdev.
This can result in a NULL pointer dereference when calling netifcarrier{on,off}().
Fix this by bailing early when processing an event reported for the CPU port. Problem was only observed when running on top of a buggy emulator.
