"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/vmalloc: fix page mapping if vm_area_alloc_pages() with high order fallback to order 0\n\nThe __vmap_pages_range_noflush() assumes its argument pages** contains\npages with the same page shift. However, since commit e9c3cda4d86e (\"mm,\nvmalloc: fix high order __GFP_NOFAIL allocations\"), if gfp_flags includes\n__GFP_NOFAIL with high order in vm_area_alloc_pages() and page allocation\nfailed for high order, the pages** may contain two different page shifts\n(high order and order-0). This could lead __vmap_pages_range_noflush() to\nperform incorrect mappings, potentially resulting in memory corruption.\n\nUsers might encounter this as follows (vmap_allow_huge = true, 2M is for\nPMD_SIZE):\n\nkvmalloc(2M, __GFP_NOFAIL|GFP_X)\n __vmalloc_node_range_noprof(vm_flags=VM_ALLOW_HUGE_VMAP)\n vm_area_alloc_pages(order=9) ---> order-9 allocation failed and fallback to order-0\n vmap_pages_range()\n vmap_pages_range_noflush()\n __vmap_pages_range_noflush(page_shift = 21) ----> wrong mapping happens\n\nWe can remove the fallback code because if a high-order allocation fails,\n__vmalloc_node_range_noprof() will retry with order-0. Therefore, it is\nunnecessary to fallback to order-0 here. Therefore, fix this by removing\nthe fallback code."
