  3. CVE-2022-49987
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: md: llamada a __md_stop_writes en md_stop. En el enlace [1], podemos ver que raid1d se ejecutaba incluso después de la ruta raid_dtr -> md_stop -> __md_stop. Primero detengamos la escritura en el destructor para alinearla con el comando md-raid normal y solucionar el problema de KASAN.
