CVE-2026-80720

A flaw was found in the iomap component of the Linux kernel. The iomapsplitioend function can cause a deadlock when it attempts to split bios that originate from iomapioendbioset and the bioset is exhausted. This can lead to a system hang, resulting in a Denial of Service DoS for affected systems...

Linux Distros Unpatched Vulnerability : CVE-2026-80720

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - iomap: add a separate bioset for iomapsplitioend iomapsplitioend can split bios that already come from iomapioendbioset and thus deadlock when the bioset is...

CVE-2026-80720

CVE-2026-80720 affects the Linux kernel iomap subsystem (file ioend.c). The root cause is that iomap_split_ioend can split block I/O requests (bios) that were already allocated from the shared iomap_ioend_bioset, creating a deadlock when that bioset becomes exhausted. The fix introduces a separat...

CVE-2026-80720 iomap: add a separate bio_set for iomap_split_ioend

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