Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:md: Fix missing release of active_io for flushsubmit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* flush io is done first */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io is not released if (atomic_dec_and_test(&mddev->flush_pending)) -> missing release of active_ioFor consequence, mddev_suspend() will wait for active_io to be zeroforever.Fix this problem by releasing active_io in submit_flushes() if flush_pending is decreased to zero.

CVE-2024-27023

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

md: Fix missing release of 'active_io' for flush

submit_flushes
atomic_set(&mddev->flush_pending, 1);
rdev_for_each_rcu(rdev, mddev)
atomic_inc(&mddev->flush_pending);
bi->bi_end_io = md_end_flush
submit_bio(bi);
/* flush io is done first */
md_end_flush
if (atomic_dec_and_test(&mddev->flush_pending))
percpu_ref_put(&mddev->active_io)
-> active_io is not released

if (atomic_dec_and_test(&mddev->flush_pending))
-> missing release of active_io

For consequence, mddev_suspend() will wait for 'active_io' to be zero
forever.

Fix this problem by releasing 'active_io' in submit_flushes() if
'flush_pending' is decreased to zero.
