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: independent PMD page
 table shared count The folio refcount may be increased unexpectly through try_get_folio() by caller such
 as split_huge_pages. In huge_pmd_unshare(), we use refcount to check whether a pmd page table is shared.
 The check is incorrect if the refcount is increased by the above caller, and this can cause the page table
 leaked: BUG: Bad page state in process sh pfn:109324 page: refcount:0 mapcount:0 mapping:0000000000000000

 may be triggered by damon, offline_page, page_idle, etc, which will increase the refcount of page table.
 1. The page table itself will be discarded after reporting the "nonzero mapcount". 2. The HugeTLB page
 mapped by the page table miss freeing since we treat the page table as shared and a shared page table will
 not be unmapped. Fix it by introducing independent PMD page table shared count. As described by comment,
 pt_index/pt_mm/pt_frag_refcount are used for s390 gmap, x86 pgds and powerpc, pt_share_count is used for
 x86/arm64/riscv pmds, so we can reuse the field as pt_share_count. (CVE-2024-57883)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.164.4 or later.
