Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 存在安全漏洞，该漏洞源于在ufshcd_clear_cmd与完成ISR竞争时，请求的mq_hctx指针的已完成标签可能被ISR设置为NULL，导致ufshcd_mcq_req_to_hwq调用时出现空指针内核错误（KE）。

scsi: ufs: core: Fix ufshcd_clear_cmd racing issue
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: 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: dump_backtrace+0xf8/0x148 show_stack+0x18/0x24 dump_stack_lvl+0x60/0x7c dump_stack+0x18/0x3c mrdump_common_die+0x24c/0x398 [mrdump] ipanic_die+0x20/0x34 [mrdump] notify_die+0x80/0xd8 die+0x94/0x2b8 __do_kernel_fault+0x264/0x298 do_page_fault+0xa4/0x4b8 do_translation_fault+0x38/0x54 do_mem_abort+0x58/0x118 el1_abort+0x3c/0x5c el1h_64_sync_handler+0x54/0x90 el1h_64_sync+0x68/0x6c blk_mq_unique_tag+0x8/0x14 ufshcd_clear_cmd+0x34/0x118 [ufs_mediatek_mod_ise] ufshcd_try_to_abort_task+0x2c8/0x5b4 [ufs_mediatek_mod_ise] ufshcd_err_handler+0xa7c/0xfa8 [ufs_mediatek_mod_ise] process_one_work+0x208/0x4fc worker_thread+0x228/0x438 kthread+0x104/0x1d4 ret_from_fork+0x10/0x20
