In the Linux kernel, the following vulnerability has been resolved:
mm/hugememory: don't unpoison hugezero_folio
When I did memory failure tests recently, below panic occurs:

The root cause is that HWPoison flag will be set for hugezerofolio without increasing the folio refcnt. But then unpoisonmemory() will decrease the folio refcnt unexpectedly as it appears like a successfully hwpoisoned folio leading to VMBUGONPAGE(pagerefcount(page) == 0) when releasing hugezerofolio.
Skip unpoisoning hugezerofolio in unpoisonmemory() to fix this issue. We're not prepared to unpoison hugezero_folio yet.
