Chainguard: linux-desktop-7.2-bootc: security update to 7.2.7-r0

medium Tenable Self-Hosted Container Security Plugin ID 474657

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-98139)

Solution

Update the linux-desktop-7.2-bootc library and its related packages to version 7.2.7-r0 or later.
