Summary
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 ...
