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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/vmalloc.c"],"versions":[{"version":"fe5c2bdcb14c8612eb5e7a09159801c7219e9ac4","lessThan":"fd1ffbb50ef4da5e1378a46616b6d7407dc795da","status":"affected","versionType":"git"},{"version":"e9c3cda4d86e56bf7fe403729f38c4f0f65d3860","lessThan":"de7bad86345c43cd040ed43e20d9fad78a3ee59f","status":"affected","versionType":"git"},{"version":"e9c3cda4d86e56bf7fe403729f38c4f0f65d3860","lessThan":"c91618816f4d21fc574d7577a37722adcd4075b2","status":"affected","versionType":"git"},{"version":"e9c3cda4d86e56bf7fe403729f38c4f0f65d3860","lessThan":"61ebe5a747da649057c37be1c37eb934b4af79ca","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/vmalloc.c"],"versions":[{"version":"6.3","status":"affected"},{"version":"0","lessThan":"6.3","status":"unaffected","versionType":"semver"},{"version":"6.1.107","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.48","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.7","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.95","versionEndExcluding":"6.1.107"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.6.48"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.10.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/fd1ffbb50ef4da5e1378a46616b6d7407dc795da"},{"url":"https://git.kernel.org/stable/c/de7bad86345c43cd040ed43e20d9fad78a3ee59f"},{"url":"https://git.kernel.org/stable/c/c91618816f4d21fc574d7577a37722adcd4075b2"},{"url":"https://git.kernel.org/stable/c/61ebe5a747da649057c37be1c37eb934b4af79ca"}],"title":"mm/vmalloc: fix page mapping if vm_area_alloc_pages() with high order fallback to order 0","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-29T15:47:43.491220Z","id":"CVE-2024-45022","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-29T15:47:57.703Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:15:32.309Z"}}]}}
