Score 4.7 from GitHub Security Advisory published 2024-10-21. NVD baseline CVSS 4.7; sources differ by 0.0.
In the Linux kernel, the following vulnerability has been resolved:
mm/gup: fix memfd_pin_folios alloc race panic
If memfd_pin_folios tries to create a hugetlb page, but someone else already did, then folio gets the value -EEXIST here:
folio = memfd_alloc_folio(memfd, start_idx); if (IS_ERR(folio)) { ret = PTR_ERR(folio); if (ret != -EEXIST) goto err;
then on the next trip through the "while start_idx" loop we panic here:
if (folio) { folio_put(folio);
To fix, set the folio to NULL on error.
