CVE-2026-80720 in Linux
Riassunto
di MITRE • 28/08/2026
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 <[email protected]> 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.
