Fix this everywhere\nby forcing 64-bit multiplication. Extract this formula into separate\nsmall helper and use it consistently in various places.\n\nSpeculative-preventing formula utilizing index_mask trick is left as is,\nbut explicit u64 casts are added in both places.","state":0,"publishedAt":"2025-06-18T11:03:20.997+00:00","modifiedAt":"2026-10-15T21:31:18.591+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"kernel/bpf/arraymap.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"c85d69135a9175c50a823d04d62d932312d037b3\",\n                            \"lessThan\": \"063e092534d4c6785228e5b1eb6e9329f66ccbe4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"c85d69135a9175c50a823d04d62d932312d037b3\",\n                            \"lessThan\": \"3c7256b880b3a5aa1895fd169a34aa4224a11862\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"c85d69135a9175c50a823d04d62d932312d037b3\",\n                            \"lessThan\": \"87ac0d600943994444e24382a87aa19acc4cd3d4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"kernel/bpf/arraymap.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"5.3\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"5.18.18\",\n                            \"lessThanOrEqual\": \"5.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"5.19.2\",\n                            \"lessThanOrEqual\": \"5.19.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.0\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/063e092534d4c6785228e5b1eb6e9329f66ccbe4","https://git.kernel.org/stable/c/3c7256b880b3a5aa1895fd169a34aa4224a11862","https://git.kernel.org/stable/c/87ac0d600943994444e24382a87aa19acc4cd3d4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-50167","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-50167","identifiers":["CVE-2022-50167"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
