  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/cxgb4: Cancel reg_work before freeing device on remove\n\nc4iw_uld_state_change() queues reg_work to register the RDMA device.\nc4iw_remove() can free ctx->dev while this work is pending or running,\nleaving c4iw_register_device() accessing the freed device.\n\nCancel reg_work before removing the device.  The registration work can\ntear down ctx->dev when registration fails, so do not unregister or\ndeallocate it again in that case.\n\nThis issue was found by an in-house static analysis tool.",
