Modified After Enrichment

This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.

Description

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. root@ls1028ardb:~# ip link set eno0 vf 1 mac 00:0c:e7:66:77:89 [ 173.543315] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000004 [ 173.637254] pc : enetc_pf_set_vf_mac+0x3c/0x80 Message from sy [ 173.641973] lr : do_setlink+0x4a8/0xec8 [ 173.732292] Call trace: [ 173.734740] enetc_pf_set_vf_mac+0x3c/0x80 [ 173.738847] __rtnl_newlink+0x530/0x89c [ 173.742692] rtnl_newlink+0x50/0x7c [ 173.746189] rtnetlink_rcv_msg+0x128/0x390 [ 173.750298] netlink_rcv_skb+0x60/0x130 [ 173.754145] rtnetlink_rcv+0x18/0x24 [ 173.757731] netlink_unicast+0x318/0x380 [ 173.761665] netlink_sendmsg+0x17c/0x3c8
