Vulnerability details

In the Linux kernel, the following vulnerability has been resolved: ice: fix double free in ice_sf_eth_activate() error path When auxiliary_device_add() fails, ice_sf_eth_activate() jumps to aux_dev_uninit and calls auxiliary_device_uninit(&sf_dev->adev). The device release callback ice_sf_dev_release() frees sf_dev, but the current error path…

falls through to sf_dev_free and calls kfree(sf_dev) again, causing a double free. Keep kfree(sf_dev) for the auxiliary_device_init() failure path, but avoid falling through to sf_dev_free after auxiliary_device_uninit().
