Overview
CVE-2026-72370 is a known-severity vulnerability. It was published on August 15, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
iomap: release pages on atomic dio size mismatch
If bio_iov_iter_get_pages() or the bounce helper succeeds but builds a
short bio, the REQ_ATOMIC size check rejects it before submission. The
old error path only dropped the bio reference, leaving any pages already
attached to the bio unreleased.
Release or unbounce the pages before falling through to out_put_bio on
this error path.
