Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

mm/huge_memory: don’t unpoison huge_zero_folio

When I did memory failure tests recently, below panic occurs:

The root cause is that HWPoison flag will be set for huge_zero_folio without increasing the folio refcnt. But then unpoison_memory() will decrease the folio refcnt unexpectedly as it appears like a successfully hwpoisoned folio leading to VM_BUG_ON_PAGE(page_ref_count(page) == 0) when releasing huge_zero_folio.

Skip unpoisoning huge_zero_folio in unpoison_memory() to fix this issue. We’re not prepared to unpoison huge_zero_folio yet.
