Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.151.80

medium Tenable Self-Hosted Container Security Plugin ID 451694

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/vmalloc: fix page mapping if
 vm_area_alloc_pages() with high order fallback to order 0 The __vmap_pages_range_noflush() assumes its
 argument pages** contains pages with the same page shift. However, since commit e9c3cda4d86e ("mm,
 vmalloc: fix high order __GFP_NOFAIL allocations"), if gfp_flags includes __GFP_NOFAIL with high order in
 vm_area_alloc_pages() and page allocation failed for high order, the pages** may contain two different
 page shifts (high order and order-0). This could lead __vmap_pages_range_noflush() to perform incorrect
 mappings, potentially resulting in memory corruption. Users might encounter this as follows
 (vmap_allow_huge = true, 2M is for PMD_SIZE): kvmalloc(2M, __GFP_NOFAIL|GFP_X)
 __vmalloc_node_range_noprof(vm_flags=VM_ALLOW_HUGE_VMAP) vm_area_alloc_pages(order=9) ---> order-9
 allocation failed and fallback to order-0 vmap_pages_range() vmap_pages_range_noflush()
 __vmap_pages_range_noflush(page_shift = 21) ----> wrong mapping happens We can remove the fallback code
 because if a high-order allocation fails, __vmalloc_node_range_noprof() will retry with order-0.
 Therefore, it is unnecessary to fallback to order-0 here. Therefore, fix this by removing the fallback
 code. (CVE-2024-45022)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.151.80 or later.
