CVE-2026-98974In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchange-range-to-eof file size exchange Norbert Szetei posted a patch containing an incomplete... Executive summary The Linux kernel's XFS filesystem has a flaw in its exchange-range file operation that can leave a file sharing data blocks past its end, so a local user could overwrite data they should not be able to change. The advisory does not state a severity score or whether it is being exploited, and it does not give a fix version or workaround. Technical summary The flaw is incorrect file size handling in XFS_IOC_EXCHANGE_RANGE when the TO_EOF flag is used with a nonzero offset. The code swaps on-disk and in-core sizes, which lets a file keep shared blocks beyond EOF and lets a later exchange clear the reflink flag, so an extending write can rewrite a block shared with another file. The advisory describes a multi-step local sequence using reflink and exchange-range on a filesystem where mkfs.xfs enables both by default, but it does not include the proof of concept. Affected kernel versions, fixed versions, workarounds, and detection guidance are not stated. A CVSS score and exploitation status are also not stated.
