This triggers\nwhen the user reads from /dev/hwrng into memory also mmap-ed from\n/dev/hwrng. The resulting page fault triggers a recursive read\nwhich then dead-locks.\n\nFix this by using a stack buffer when calling copy_to_user." } ] }, "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": "9996508b3353", "version_value": "eafd83b92f6c" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "2.6.33", "status": "affected" }, { "version": "0", "lessThan": "2.6.33", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.307", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.269", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.210", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.149", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.76", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.15", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.3", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/eafd83b92f6c044007a3591cbd476bcf90455990", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/eafd83b92f6c044007a3591cbd476bcf90455990" }, { "url": "https://git.kernel.org/stable/c/5030d4c798863ccb266563201b341a099e8cdd48", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/5030d4c798863ccb266563201b341a099e8cdd48" }, { "url": "https://git.kernel.org/stable/c/c6a8111aacbfe7a8a70f46cc0de8eed00561693c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/c6a8111aacbfe7a8a70f46cc0de8eed00561693c" }, { "url": "https://git.kernel.org/stable/c/26cc6d7006f922df6cc4389248032d955750b2a0", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/26cc6d7006f922df6cc4389248032d955750b2a0" }, { "url": "https://git.kernel.org/stable/c/aa8aa16ed9adf1df05bb339d588cf485a011839e", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/aa8aa16ed9adf1df05bb339d588cf485a011839e" }, { "url": "https://git.kernel.org/stable/c/ecabe8cd456d3bf81e92c53b074732f3140f170d", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ecabe8cd456d3bf81e92c53b074732f3140f170d" }, { "url": "https://git.kernel.org/stable/c/6822a14271786150e178869f1495cc03e74c5029", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/6822a14271786150e178869f1495cc03e74c5029" }, { "url": "https://git.kernel.org/stable/c/78aafb3884f6bc6636efcc1760c891c8500b9922", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/78aafb3884f6bc6636efcc1760c891c8500b9922" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
