  "description": "In the Linux kernel, the following vulnerability has been resolved:  igc: don\u0027t fail igc_probe() on LED setup error  When igc_led_setup() fails, igc_probe() fails and triggers kernel panic in free_netdev() since unregister_netdev() is not called. [1] This behavior can be tested using fault-injection framework, especially the failslab feature. [2]  Since LED support is not mandatory, treat LED setup failures as non-fatal and continue probe with a warning message, consequently avoiding the kernel panic.
