CVE-2026-80538: xfs: propagate errors from xfs_rtginode_load

Published Aug 26, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved:

xfs: propagate errors from xfsrtginodeload

xfsrtginodeensure() treats every xfsrtginodeload() error other than -ENOENT as success. This can leave the realtime group inode unset after an I/O, allocation, or corruption error. Growfs then continues as though the inode had been loaded.

Only -ENOENT means that the inode needs to be created. Return all other errors to the growfs caller.

Description

Frequently Asked Questions

Which deployments are relevant to this issue?

The issue is relevant to XFS filesystems using realtime groups when a growfs operation causes the realtime group inode to be loaded. It is triggered when that load encounters an I/O, allocation, or filesystem-corruption error other than -ENOENT.

What error condition leads to unsafe growfs behavior?

Before the fix, xfs_rtginode_ensure() treated every xfs_rtginode_load() error except -ENOENT as success. This allowed growfs to continue even though the realtime group inode had not been set; -ENOENT is the only condition that should cause creation of the inode.
