Therefore we do not expect to see VM_FAULT_HWPOISON in\ndo_exception().\n\nHowever, since commit af19487f00f3 (\"mm: make PTE_MARKER_SWAPIN_ERROR more\ngeneral\"), it is possible to see VM_FAULT_HWPOISON in combination with\nPTE_MARKER_POISONED, even on architectures that do not support HWPOISON\notherwise. In this case, we will end up on the BUG() in do_exception().\n\nFix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar\nto x86 when MEMORY_FAILURE is not configured. Also print unexpected fault\nflags, for easier debugging.\n\nNote that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot\nsupport swap entries on other levels than PTE level." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "af19487f00f3", "version_value": "73a9260b7366" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "6.6", "status": "affected" }, { "version": "0", "lessThan": "6.6", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.44", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.12", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.2", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/73a9260b7366d2906ec011e100319359fe2277d0", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/73a9260b7366d2906ec011e100319359fe2277d0" }, { "url": "https://git.kernel.org/stable/c/9e13767ccefdc4f8aa92514b592b60f6b54882ff", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/9e13767ccefdc4f8aa92514b592b60f6b54882ff" }, { "url": "https://git.kernel.org/stable/c/a3aefb871222a9880602d1a44a558177b4143e3b", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/a3aefb871222a9880602d1a44a558177b4143e3b" }, { "url": "https://git.kernel.org/stable/c/df39038cd89525d465c2c8827eb64116873f141a", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/df39038cd89525d465c2c8827eb64116873f141a" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
