CVE-2024-27023 md: Fix missing release of 'active_io' for flush

In the Linux kernel, the following vulnerability has been resolved: md: Fix missing release of 'activeio' for flush submitflushes atomicset&mddev-flushpending, 1; rdevforeachrcurdev, mddev atomicinc&mddev-flushpending; bi-biendio = mdendflush submitbiobi; / flush io is done first / mdendflush if...

CVE-2024-27023

In CVE-2024-27023, the Linux kernel md subsystem (md) had a flaw where active_io was not released when flush_pending fell to zero, causing mddev_suspend() to wait forever. The fix releases active_io in submit_flushes() as soon as flush_pending transitions to zero, preventing the hang. The descrip...
