"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nima: verify the previous kernel's IMA buffer lies in addressable RAM\n\nPatch series \"Address page fault in ima_restore_measurement_list()\", v3.\n\nWhen the second-stage kernel is booted via kexec with a limiting command\nline such as \"mem=<size>\" we observe a pafe fault that happens.\n\n BUG: unable to handle page fault for address: ffff97793ff47000\n RIP: ima_restore_measurement_list+0xdc/0x45a\n #PF: error_code(0x0000) not-present page\n\nThis happens on x86_64 only, as this is already fixed in aarch64 in\ncommit: cbf9c4b9617b (\"of: check previous kernel's ima-kexec-buffer\nagainst memory bounds\")\n\n\nThis patch (of 3):\n\nWhen the second-stage kernel is booted with a limiting command line (e.g. \n\"mem=<size>\"), the IMA measurement buffer handed over from the previous\nkernel may fall outside the addressable RAM of the new kernel. Accessing\nsuch a buffer can fault during early restore.\n\nIntroduce a small generic helper, ima_validate_range(), which verifies\nthat a physical [start, end] range for the previous-kernel IMA buffer lies\nwithin addressable memory:\n\t- On x86, use pfn_range_is_mapped().\n\t- On OF based architectures, use page_is_ram()."
