一、漏洞信息
漏洞编号:CVE-2024-26671
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V2.0分值:
BaseScore:0.0 Low
Vector:CVSS:2.0/
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:blk-mq: fix IO hang from sbitmap wakeup raceIn blk_mq_mark_tag_wait(), __add_wait_queue() may be re-orderedwith the following blk_mq_get_driver_tag() in case of getting drivertag failure.Then in __sbitmap_queue_wake_up(), waitqueue_active() may not observethe added waiter in blk_mq_mark_tag_wait() and wake up nothing, meantimeblk_mq_mark_tag_wait() can t get driver tag successfully.This issue can be reproduced by running the following test in loop, andfio hang can be observed in < 30min when running it on my test VMin laptop. modprobe -r scsi_debug modprobe scsi_debug delay=0 dev_size_mb=4096 max_queue=1 host_max_queue=1 submit_queues=4 dev=ls -d /sys/bus/pseudo/drivers/scsi_debug/adapter*/host*/target*/*/block/* | head -1 | xargs basename
fio --filename=/dev/ $dev --direct=1 --rw=randrw --bs=4k --iodepth=1 --runtime=100 --numjobs=40 --time_based --name=test --ioengine=libaioFix the issue by adding one explicit barrier in blk_mq_mark_tag_wait(), whichis just fine in case of running out of tag.
