CVE-2026-98445

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.
