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: initialize gigantic
bootmem hugepage struct pages earlier Gigantic bootmem HugeTLB pages are currently initialized from
hugetlb_init(), but page_alloc_init_late() runs earlier and walks pageblocks to determine zone contiguity.
If a bootmem HugeTLB region is marked noinit, set_zone_contiguous() can observe still-uninitialized struct
pages through __pageblock_pfn_to_page(). This may not trigger an immediate failure, but it can make
set_zone_contiguous() compute the wrong zone contiguity state. If extra poisoned-page checks are added in
this path, such as PF_POISONED_CHECK() in page_zone_id(), it can also trigger an early boot panic.
Initialize gigantic bootmem HugeTLB struct pages from page_alloc_init_late(), before zone contiguity is
evaluated, so later page allocator setup only sees valid struct page state. This also makes the
initialization order more natural, as struct pages should be initialized before later code inspects them.
(CVE-2026-93230)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
