Next, the acpi_nfit_init() failure causes\nacpi_nfit_probe() to fail, the acpi_desc object is freed, and a\ndangling pointer is left behind in the acpi_descs. Any subsequent\nACPI Machine Check Exception will trigger nfit_handle_mce() which\niterates over acpi_descs and so a use-after-free will occur.\n\nMoreover, if acpi_nfit_probe() returns 0 after installing a notify\nhandler for the NFIT device and without allocating the acpi_desc\nobject and setting the NFIT device's driver data pointer, the\nacpi_desc object will be allocated by acpi_nfit_update_notify()\nand acpi_nfit_init() will be called to initialize it. Regardless\nof whether or not acpi_nfit_init() fails in that case, the\nacpi_nfit_shutdown() devm action is not added for the NFIT device\nand acpi_desc is never removed from the acpi_descs list. If the\nacpi_desc object is freed subsequently on driver removal, any\nsubsequent ACPI MCE will lead to a use-after-free like in the\nprevious case.\n\nTo address the first issue mentioned above, make acpi_nfit_probe()\ncall acpi_nfit_shutdown() directly on acpi_nfit_init() failures and\nto address the other one, add a remove callback to the driver and\nmake it call acpi_nfit_shutdown(). Also, since it is now possible to\npass NULL to acpi_nfit_shutdown() or the acpi_desc object passed to it\nmay not have been initialized, add checks against NULL for acpi_desc and\nits nvdimm_bus field to that function and make acpi_nfit_unregister()\nclear the latter after unregistering the NVDIMM bus.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "ee82078e776ae31266cc70fdf62ac17c3c6f100a" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "6ff054cc02a763914773b026cacb429e5fbf64fa" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "b07d22a2d17ad6465c87bd5752bc70e4c16e0ee4" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "c127dbd832bd4b9aef8a749d9f491b74042f9b47" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "df7c92216a1583a76cb0cbf2f21cd68870609b05" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "3b2628f7682aea8d9ce09ad4b9a3bd144b451eaa" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "7d69235bdc581a4346e9bcd6a8bea37d3e1abd25" }, { "version": "a61fe6f7902ecaa89d5e6c709490fc4324927134", "status": "affected", "versionType": "git", "lessThan": "38bf27511ef41bffebd157ec3eba41fc89ba59cd" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "4.6", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "4.6" }, { "version": "5.10.261", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.212", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.178", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.145", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.97", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.40", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "7.1.4", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.1.*" }, { "version": "7.2", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
