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: block: add pgmap check to
 biovec_phys_mergeable biovec_phys_mergeable() is used by the request merge, DMA mapping, and integrity
 merge paths to decide if two physically contiguous bvec segments can be coalesced into one. It currently
 has no check for whether the segments belong to different dev_pagemaps. When zone device memory is
 registered in multiple chunks, each chunk gets its own dev_pagemap. A single bio can legitimately contain
 bvecs from different pgmaps -- iov_iter_extract_bvecs() breaks at pgmap boundaries but the outer loop in
 bio_iov_iter_get_pages() continues filling the same bio. If such bvecs are physically contiguous,
 biovec_phys_mergeable() will coalesce them, making it impossible to recover the correct pgmap for the
 merged segment via page_pgmap(). Add a zone_device_pages_have_same_pgmap() check to prevent merging bvec
 segments that span different pgmaps. (CVE-2026-46115)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.613.40 or later.
