CVE-2026-98139

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

ntfs: only count successfully cleared runs when freeing clusters

ntfs_cluster_free_from_rl_nolock() adds a run's length to nr_freed

whenever the error bookkeeping condition is false, which includes

cases where ntfs_bitmap_clear_run() actually failed - e.g. a second

run failing with the same errno as an earlier one, or any failure

after a non-ENOMEM error was already recorded. Since a failed

ntfs_bitmap_clear_run() rolls back its partial modifications, no

bits were cleared for that run, yet its length still inflates

vol->free_clusters, corrupting statfs output and the allocator's

free space gate.

Only count runs whose bitmap clear succeeded.
