Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix folio is still mapped
 when deleted Migration may be raced with fallocating hole. remove_inode_single_folio will unmap the folio
 if the folio is still mapped. However, it's called without folio lock. If the folio is migrated and the
 mapped pte has been converted to migration entry, folio_mapped() returns false, and won't unmap it. Due to
 extra refcount held by remove_inode_single_folio, migration fails, restores migration entry to normal pte,
 and the folio is mapped again. As a result, we triggered BUG in filemap_unaccount_folio. The log is as
 follows: BUG: Bad page cache in process hugetlb pfn:156c00 page: refcount:515 mapcount:0
