Detail

In the Linux kernel, the following vulnerability has been resolved:

net: enetc: allocate vf_state during PF probes

In the previous implementation, vf_state is allocated memory only when VF is enabled. However, net_device_ops::ndo_set_vf_mac() may be called before VF is enabled to configure the MAC address of VF. If this is the case, enetc_pf_set_vf_mac() will access vf_state, resulting in access to a null pointer. The simplified error log is as follows.
