Description OSIDB Bzimport 2025-04-16 15:06:18 UTC 
In the Linux kernel, the following vulnerability has been resolved:

block: fix adding folio to bio

>4GB folio is possible on some ARCHs, such as aarch64, 16GB hugepage
is supported, then 'offset' of folio can't be held in 'unsigned int',
cause warning in bio_add_folio_nofail() and IO failure.

Fix it by adjusting 'page' & trimming 'offset' so that `->bi_offset` won't
be overflow, and folio can be added to bio successfully.
