In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Cancel reg_work before freeing device on remove
c4iw_uld_state_change() queues reg_work to register the RDMA device. c4iw_remove() can free ctx->dev while this work is pending or running, leaving c4iw_register_device() accessing the freed device.
Cancel reg_work before removing the device. The registration work can tear down ctx->dev when registration fails, so do not unregister or deallocate it again in that case.
This issue was found by an in-house static analysis tool.
