Title
ACPI: NFIT: core: Fix acpi_nfit_init() error cleanup
Summary
In the Linux kernel, the following vulnerability has been resolved: ACPI: NFIT: core: Fix acpi_nfit_init() error cleanup If acpi_nfit_init() fails after adding the acpi_desc object to the acpi_descs list, that object is never removed from that list because the acpi_nfit_shutdown() devm action is not added for the NFIT device in that case. Next, the acpi_nfit_init() failure causes acpi_nfit_probe() to fail, the acpi_desc object is freed, and a dangling pointer is left behind in the acpi_descs. Any subsequent ACPI Machine Check Exception will trigger nfit_handle_mce() which iterates over acpi_descs and so a use-after-free will occur. Moreover, if acpi_nfit_probe() returns 0 after installing a notify handler for the NFIT device and without allocating the acpi_desc object and setting the NFIT device's driver data pointer, the acpi_desc object will be allocated by acpi_nfit_update_notify() and acpi_nfit_init() will be called to initialize it. Regardless of whether or not acpi_nfit_init() fails in that case, the acpi_nfit_shutdown() devm action is not added for the NFIT device and acpi_desc is never removed from the acpi_descs list. If the acpi_desc object is freed subsequently on driver removal, any subsequent ACPI MCE will lead to a use-after-free like in the previous case. To address the first issue mentioned above, make acpi_nfit_probe() call acpi_nfit_shutdown() directly on acpi_nfit_init() failures and to address the other one, add a remove callback to the driver and make it call acpi_nfit_shutdown(). Also, since it is now possible to pass NULL to acpi_nfit_shutdown() or the acpi_desc object passed to it may not have been initialized, add checks against NULL for acpi_desc and its nvdimm_bus field to that function and make acpi_nfit_unregister() clear the latter after unregistering the NVDIMM bus.

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\u0027s 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\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/acpi/nfit/core.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"ee82078e776ae31266cc70fdf62ac17c3c6f100a\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"6ff054cc02a763914773b026cacb429e5fbf64fa\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"b07d22a2d17ad6465c87bd5752bc70e4c16e0ee4\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"c127dbd832bd4b9aef8a749d9f491b74042f9b47\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"df7c92216a1583a76cb0cbf2f21cd68870609b05\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"3b2628f7682aea8d9ce09ad4b9a3bd144b451eaa\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"7d69235bdc581a4346e9bcd6a8bea37d3e1abd25\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a61fe6f7902ecaa89d5e6c709490fc4324927134\",\"lessThan\":\"38bf27511ef41bffebd157ec3eba41fc89ba59cd\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/acpi/nfit/core.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"4.6\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"4.6\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.10.261\",\"lessThanOrEqual\":\"5.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.212\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.178\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.145\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.97\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.18.40\",\"lessThanOrEqual\":\"6.18.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.1.4\",\"lessThanOrEqual\":\"7.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.2-rc1\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/38bf27511ef41bffebd157ec3eba41fc89ba59cd\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/3b2628f7682aea8d9ce09ad4b9a3bd144b451eaa\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/6ff054cc02a763914773b026cacb429e5fbf64fa\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/7d69235bdc581a4346e9bcd6a8bea37d3e1abd25\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/b07d22a2d17ad6465c87bd5752bc70e4c16e0ee4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/c127dbd832bd4b9aef8a749d9f491b74042f9b47\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/df7c92216a1583a76cb0cbf2f21cd68870609b05\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/ee82078e776ae31266cc70fdf62ac17c3c6f100a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}"
