- In the Linux kernel, the following vulnerability has been resolved: iomap: add a separate bio_set for
iomap_split_ioend iomap_split_ioend can split bios that already come from iomap_ioend_bioset and thus
deadlock when the bioset is exhausted. Add a separate bio_set to avoid this deadlock. Christian Brauner
