"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: stratix10-rsu: Fix NULL deref on rsu_send_msg() timeout in probe\n\nrsu_send_msg() can return -ETIMEDOUT when\nwait_for_completion_interruptible_timeout() fires while the SMC call is still\npending. In stratix10_rsu_probe(), the error paths for COMMAND_RSU_DCMF_VERSION,\nCOMMAND_RSU_DCMF_STATUS, COMMAND_RSU_MAX_RETRY and COMMAND_RSU_GET_SPT_TABLE\ncall stratix10_svc_free_channel() - which sets chan->scl to NULL - but then\nfall through and queue the next request on the same channel. The next svc\nkthread that runs will dereference pdata->chan->scl in its receive callback\npath, triggering a NULL pointer dereference identical to the one fixed by\ncommit c45f7263100c (\"firmware: stratix10-rsu: Fix NULL pointer dereference\nwhen RSU is disabled\") for the COMMAND_RSU_STATUS path.\n\nApply the same cleanup pattern to the remaining failure paths: remove the\nasync client, free the channel, and return early so no further messages are\nqueued on a channel whose scl has been cleared.\n\nWhile at it, clean up stratix10_rsu_probe() in two ways without changing\nbehavior:\n\n- Drop redundant zero-initialization of fields already cleared by\n devm_kzalloc(): client.receive_cb, status.* and spt0/1_address\n (INVALID_SPT_ADDRESS is 0x0).\n\n- Replace five identical 3-line error-cleanup blocks\n (stratix10_svc_remove_async_client() + stratix10_svc_free_channel() +\n return ret) with goto labels (remove_async_client, free_channel),\n matching the standard kernel resource-unwinding pattern and making it\n easier to extend the probe sequence without forgetting matching\n cleanup.\n\nAlso move init_completion() next to mutex_init() so sync-primitive\ninitialization is grouped before anything that could trigger a\ncallback.\n\n---\nv2: Add a minor clean-up of the function stratix10_rsu_probe() to have a\n centralize exit for all the rsu_send_async_msg() and rsu_send_msg()."
