CVE-2022-49987 Information

Jun 19, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

md: call __md_stop_writes in md_stop

From the link [1] we can see raid1d was running even after the path raid_dtr -> md_stop -> __md_stop.

Let’s stop write first in destructor to align with normal md-raid to fix the KASAN issue.
