This brings the bloom map in line with\nmany other map types.\n\nThe lack of this protection can cause kernel crashes for value sizes\nthat overflow int's. Such a crash was caught by syzkaller. The next\npatch adds more guard-rails at a lower 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": "9330986c0300", "version_value": "fa6995eeb62e" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "5.16", "status": "affected" }, { "version": "0", "lessThan": "5.16", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.91", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.31", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.10", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/fa6995eeb62e74b5a1480c73fb7b420c270784d3", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/fa6995eeb62e74b5a1480c73fb7b420c270784d3" }, { "url": "https://git.kernel.org/stable/c/608e13706c8b6c658a0646f09ebced74ec367f7c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/608e13706c8b6c658a0646f09ebced74ec367f7c" }, { "url": "https://git.kernel.org/stable/c/c418afb9bf23e2f2b76cb819601e4a5d9dbab42d", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/c418afb9bf23e2f2b76cb819601e4a5d9dbab42d" }, { "url": "https://git.kernel.org/stable/c/a8d89feba7e54e691ca7c4efc2a6264fa83f3687", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/a8d89feba7e54e691ca7c4efc2a6264fa83f3687" } ] }, "generator": { "engine": "bippy-8e903de6a542" } }
