As a result, if src_pfns or dst_pfns is\ndereferenced, the null pointer dereference bug will happen.\n\nMoreover, the device is going away. If the kcalloc() fails, the pages\nmapping a chunk could not be evicted. So add a __GFP_NOFAIL flag in\nkcalloc().\n\nFinally, as there is no need to have physically contiguous memory, Switch\nkcalloc() to kvcalloc() in order to avoid failing allocations." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "lib/test_hmm.c" ], "versions": [ { "version": "b2ef9f5a5cb37643ca5def3516c546457074b882", "lessThan": "1a21fdeea502658e315bd939409b755974f4fb64", "status": "affected", "versionType": "git" }, { "version": "b2ef9f5a5cb37643ca5def3516c546457074b882", "lessThan": "65e528a69cb3ed4a286c45b4afba57461c8b5b33", "status": "affected", "versionType": "git" }, { "version": "b2ef9f5a5cb37643ca5def3516c546457074b882", "lessThan": "ce47e8ead9a72834cc68431d53f8092ce69bebb7", "status": "affected", "versionType": "git" }, { "version": "b2ef9f5a5cb37643ca5def3516c546457074b882", "lessThan": "3b20d18f475bd17309db640dbe7d7c7ebb5bc2bc", "status": "affected", "versionType": "git" }, { "version": "b2ef9f5a5cb37643ca5def3516c546457074b882", "lessThan": "c2af060d1c18beaec56351cf9c9bcbbc5af341a3", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "lib/test_hmm.c" ], "versions": [ { "version": "5.8", "status": "affected" }, { "version": "0", "lessThan": "5.8", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.93", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.33", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.12", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.3", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10", "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": "5.8", "versionEndExcluding": "6.1.93" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.6.33" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.8.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.9.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.10" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/1a21fdeea502658e315bd939409b755974f4fb64" }, { "url": "https://git.kernel.org/stable/c/65e528a69cb3ed4a286c45b4afba57461c8b5b33" }, { "url": "https://git.kernel.org/stable/c/ce47e8ead9a72834cc68431d53f8092ce69bebb7" }, { "url": "https://git.kernel.org/stable/c/3b20d18f475bd17309db640dbe7d7c7ebb5bc2bc" }, { "url": "https://git.kernel.org/stable/c/c2af060d1c18beaec56351cf9c9bcbbc5af341a3" } ], "title": "lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T04:12:25.183Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/1a21fdeea502658e315bd939409b755974f4fb64", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/65e528a69cb3ed4a286c45b4afba57461c8b5b33", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ce47e8ead9a72834cc68431d53f8092ce69bebb7", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/3b20d18f475bd17309db640dbe7d7c7ebb5bc2bc", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/c2af060d1c18beaec56351cf9c9bcbbc5af341a3", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-38543", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T17:15:10.301202Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:34:58.014Z" } } ] } }
