Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：scsi: target: core: Avoid smp_processor_id() in preemptible code The BUG message BUG: using smp_processor_id() in preemptible [00000000] code was observed for TCMU devices with kernel config DEBUG_PREEMPT. The message was observed when blktests block/005 was run on TCMU devices with fileio backend or user:zbc backend [1]. The commit 1130b499b4a7 (scsi: target: tcm_loop: Use LIO wq cmd submission helper) triggered the symptom. The commit modified work queue to handle commands and changed 'current->nr_cpu_allowed' at smp_processor_id() call. The message was also observed at system shutdown when TCMU devices were not cleaned up [2]. The function smp_processor_id() was called in SCSI host work queue for abort handling, and triggered the BUG message. This symptom was observed regardless of the commit 1130b499b4a7 (scsi: target: tcm_loop: Use LIO wq cmd submission helper). To avoid the preemptible code check at smp_processor_id(), get CPU ID with raw_smp_processor_id() instead. The CPU ID is used for performance improvement then thread move to other CPU will not affect the code.

The commit modified work queue to handle commands and changed 'current->nr_cpu_allowed' at smp_processor_id() call. The message was also observed at system shutdown when TCMU devices were not cleaned up [2]. The function smp_processor_id() was called in SCSI host work queue for abort handling, and triggered the BUG message. This symptom was observed regardless of the commit 1130b499b4a7 (scsi: target: tcm_loop: Use LIO wq cmd submission helper). To avoid the preemptible code check at smp_processor_id(), get CPU ID with raw_smp_processor_id() instead. The CPU ID is used for performance improvement then thread move to other CPU will not affect the code.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: target: core: Avoid     smp_processor_id() in preemptible code The BUG message BUG: using smp_processor_id() in preemptible     [00000000] code was observed for TCMU devices with kernel config DEBUG_PREEMPT. The message was observed     when blktests block/005 was run on TCMU devices with fileio backend or user:zbc backend [1]. The commit     1130b499b4a7 (scsi: target: tcm_loop: Use LIO wq cmd submission helper) triggered the symptom. The     commit modified work queue to handle commands and changed 'current->nr_cpu_allowed' at smp_processor_id()     call. The message was also observed at system shutdown when TCMU devices were not cleaned up [2]. The     function smp_processor_id() was called in SCSI host work queue for abort handling, and triggered the BUG     message. This symptom was observed regardless of the commit 1130b499b4a7 (scsi: target: tcm_loop: Use LIO     wq cmd submission helper). To avoid the preemptible code check at smp_processor_id(), get CPU ID with     raw_smp_processor_id() instead. The CPU ID is used for performance improvement then thread move to other     CPU will not affect the code.
