概要
遠端 Azure Linux 主機缺少一個或多個安全性更新。說明
遠端 Azure Linux 3.0 主機上安裝的核心版本比測試版舊。因此，此版本會受到 CVE-2024-41054 公告中提及的一個弱點影響。- 已解決 Linux 核心中的下列弱點：scsi: ufs: core: Fix ufshcd_clear_cmd racing issue When ufshcd_clear_cmd is racing with the completion ISR, the completed tag of the request's mq_hctx pointer will be set to NULL by the ISR. And ufshcd_clear_cmd's call to ufshcd_mcq_req_to_hwq will get NULL pointer KE. Return success when the request is completed by ISR because sq does not need cleanup.
The racing flow is: Thread A ufshcd_err_handler step 1 ufshcd_try_to_abort_task ufshcd_cmd_inflight(true) step 3 ufshcd_clear_cmd ... ufshcd_mcq_req_to_hwq blk_mq_unique_tag rq->mq_hctx->queue_num step 5 Thread B ufs_mtk_mcq_intr(cq complete ISR) step 2 scsi_done ... __blk_mq_free_request rq->mq_hctx = NULL; step 4 Below is KE back trace: ufshcd_try_to_abort_task: cmd pending in the device. tag = 6 Unable to handle kernel NULL pointer dereference at virtual address 0000000000000194 pc : [0xffffffd589679bf8] blk_mq_unique_tag+0x8/0x14 lr : [0xffffffd5862f95b4] ufshcd_mcq_sq_cleanup+0x6c/0x1cc [ufs_mediatek_mod_ise] Workqueue: ufs_eh_wq_0 ufshcd_err_handler [ufs_mediatek_mod_ise] Call trace:
