# CVE-2026-80720

> 3.1 LOW

## Beschreibung

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  says:
Mark iomap_ioend_split_bioset static as it is only used in ioend.c,
fixing the sparse warning reported by the kernel test robot.

## Patch verfügbar (OSV)

- Kernel ≥ 6.18.44
- Kernel ≥ 7.1.8
