CVE-2026-98445

/// Technical description

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

xfs: don't let memory failures leak blocks and kill repairs

LOLLM complains that a memory allocation failure in

xrep_newbt_add_blocks results in online repair leaking blocks that were

previously allocated to write a new btree, but the problem is worse than

that -- a limitation of the codebase is that the callers cannot undo the

transaction /and/ return the error -- either you undo all changes and

commit the transaction, or you error out and the filesystem goes down.

However, the new btree space reservation object isn't that big (~48

bytes). Let's just do a NOFAIL allocation and the problem goes away.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
