In the Linux kernel, the following vulnerability has been resolved: idpf: fix error handling in the init_task on load If the init_task fails during a driver load, we end up without vports and netdevs, effectively failing the entire process. In that state a subsequent reset will result in a crash as the service task attempts to access uninitialized resources. Following trace is from an error in the init_task where the CREATE_VPORT (op 501) is rejected by the FW: [40922.763136] idpf 0000:83:00.0: Device HW Reset initiated [40924.449797] idpf 0000:83:00.0: Transaction failed (op 501) [40958.14819
