- Summary
- net: enetc: allocate vf_state during PF probes
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: enetc: allocate vf_state during PF probes
In the previous implementation, vfstate is allocated memory only when VF is enabled. However, netdeviceops::ndosetvfmac() may be called before VF is enabled to configure the MAC address of VF. If this is the case, enetcpfsetvfmac() will access vf_state, resulting in access to a null pointer. The simplified error log is as follows.
