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: NFS: Charge unstable writes by request
 size, not folio size nfs_folio_mark_unstable() and nfs_folio_clear_commit() charge and uncharge
 NR_WRITEBACK/WB_WRITEBACK by folio_nr_pages(folio) once per *request* added to or removed from a commit
 list. This is correct only when a folio has a single associated request. When pg_test splits a folio into
 N sub-folio requests (e.g. pNFS flexfiles striping with a stripe unit smaller than the folio size, or
 plain wsize-limited splitting), each of the N requests independently charges the whole folio's page count,
 inflating the accounting by a factor of N per folio. With large folios and small stripe units this reaches
 multiple orders of magnitude: a 2 MiB folio split into 512 4 KiB requests can charge up to 512x its real
 size, pushing global dirty+writeback accounting past the system's dirty threshold and forcing every
 buffered writer on the host into the hard-throttle path, including unrelated in-kernel NFS server threads
 sharing the box. Charge each request only for the pages it actually covers. (CVE-2026-72132)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.731.2 or later.
