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: mm/hugetlb: restore reservation on
 error in hugetlb folio copy paths Two sites in mm/hugetlb.c allocate a hugetlb folio via
 alloc_hugetlb_folio() (consuming a VMA reservation) and then call copy_user_large_folio(), which became
 int-returning in commit 1cb9dc4b475c ("mm: hwpoison: support recovery from HugePage copy-on-write faults")
 and can now fail (e.g. -EHWPOISON on a hwpoisoned source page). On the failure path, folio_put() restores
 the global hugetlb pool count through free_huge_folio(), but the per-VMA reservation map entry is left
 marked consumed: - hugetlb_mfill_atomic_pte() resubmission path (UFFDIO_COPY) - copy_hugetlb_page_range()
 fork-time CoW path when hugetlb_try_dup_anon_rmap() fails (rare: pinned hugetlb anon folio under fork)
 User-visible effect: on UFFDIO_COPY into a private hugetlb VMA where the resubmission copy fails, the
 reservation for that address is leaked from the VMA's reserve map. A subsequent fault at the same address
 takes the no-reservation path, and under hugetlb pool pressure the task is SIGBUSed at an address it had
 previously reserved. The fork-time CoW path leaks the same way in the child VMA's reserve map, though it
 requires the much rarer combination of pinned hugetlb anon page + hwpoisoned source. Add the missing
 restore_reserve_on_error() call before folio_put() on both error paths. (CVE-2026-53154)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.3 or later.
