Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
idpf: fix possible vport_config NULL pointer deref in remove
Attempting to remove the driver will cause a crash in cases where the vport failed to initialize. Following trace is from an instance where the driver failed during an attempt to create a VF: [ 1661.543624] idpf 0000:84:00.7: Device HW Reset initiated [ 1722.923726] idpf 0000:84:00.7: Transaction timed-out (op:1 cookie:2900 vc_op:1 salt:29 timeout:60000ms) [ 1723.353263] BUG: kernel NULL pointer dereference, address: 0000000000000028 ...

Avoid the NULL pointer dereference by adding NULL pointer check for vport_config[i], before freeing user_config.q_coalesce.
