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" }, { "version": "6.1.95", "lessThan": "6.1.107", "status": "affected", "versionType": "semver" } ] }, { "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" } } ] } }
