This warning is emited if the argument\nis equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first\nverifies that a user-provided value call_pkg->nd_family of type u64 is\nnot equal to 0. Then the value is converted to int, and only after that\nis compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid\nargument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while\nthe lower 32 bits are zero.\n\nFurthermore, it is best to return EINVAL immediately upon seeing the\ninvalid user input. The WARNING is insufficient to prevent further\nundefined behavior based on other invalid user input.\n\nAll checks of the input value should be applied to the original variable\ncall_pkg->nd_family.\n\n[iweiny: update commit message]","state":0,"publishedAt":"2025-04-16T14:12:05.199+00:00","modifiedAt":"2026-10-15T21:51:56.979+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/acpi/nfit/core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"4b65cff06a004ac54f6ea8886060f0d07b1ca055\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"92ba06aef65522483784dcbd6697629ddbd4c4f9\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"bae5b55e0f327102e78f6a66fb127275e9bc91b6\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"c90402d2a226ff7afbe1d0650bee8ecc15a91049\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"e71a57c5aaa389d4c3c82f920761262efdd18d38\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"73851cfceb00cc77d7a0851bc10f2263394c3e87\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"85f11291658ab907c4294319c8102450cc75bb96\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6450ddbd5d8e83ea9927c7f9076a21f829699e0f\",\n \"lessThan\": \"2ff0e408db36c21ed3fa5e3c1e0e687c82cf132f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/acpi/nfit/core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.9\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.9\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.236\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.180\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.134\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.87\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.23\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.13.11\",\n \"lessThanOrEqual\": \"6.13.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.14.2\",\n \"lessThanOrEqual\": \"6.14.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.15\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/4b65cff06a004ac54f6ea8886060f0d07b1ca055","https://git.kernel.org/stable/c/92ba06aef65522483784dcbd6697629ddbd4c4f9","https://git.kernel.org/stable/c/bae5b55e0f327102e78f6a66fb127275e9bc91b6","https://git.kernel.org/stable/c/c90402d2a226ff7afbe1d0650bee8ecc15a91049","https://git.kernel.org/stable/c/e71a57c5aaa389d4c3c82f920761262efdd18d38","https://git.kernel.org/stable/c/73851cfceb00cc77d7a0851bc10f2263394c3e87","https://git.kernel.org/stable/c/85f11291658ab907c4294319c8102450cc75bb96","https://git.kernel.org/stable/c/2ff0e408db36c21ed3fa5e3c1e0e687c82cf132f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-22044","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-22044","identifiers":["CVE-2025-22044"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
