Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a race condition within the enetc_vf_set_features() and enetc_vf_netdev_setup() functions in drivers/net/ethernet/freescale/enetc/enetc_vf.c, within the enetc_pf_set_features() function in drivers/net/ethernet/freescale/enetc/enetc_pf.c, within the enetc_close() and enetc_setup_tc_mqprio() functions in drivers/net/ethernet/freescale/enetc/enetc.c, within the fsl-enetc-$() function in drivers/net/ethernet/freescale/enetc/Makefile. A local user can perform a denial of service (DoS) attack.
