CVE-2022-49987 Details
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. [1]. https://lore.kernel.org/linux-raid/CAPhsuW5gc4AakdGNdF8ubpezAuDLFOYUO_sfMZcec6hQFm8nhg@mail.gmail.com/T/#m7f12bf90481c02c6d2da68c64aeed4779b7df74a
A vulnerability in the Linux kernel's RAID1 implementation has been addressed. The issue arose because the RAID1 'd' thread continued to operate even after the RAID device was instructed to stop, leading to a Kernel Address Sanitizer (KASAN) issue. The vulnerability has been resolved by modifying the write operation sequence to align with standard RAID management practices.
