{"schema":"threatline.record/2","record":{"id":"CVE-2026-98222","aliases":[],"summary":"KEYS: encrypted: fix integer overflow of datablob_len","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nKEYS: encrypted: fix integer overflow of datablob_len\n\nencrypted_key_alloc() stores datablob_len in a u16. It is computed from\nmultiple string and payload lengths. If the result exceeds U16_MAX, the\nassignment truncates the allocation size. KASAN reports a 32760-byte\nslab-out-of-bounds write when __ekey_init() copies the master key\ndescription into the undersized buffer.\n\nThe total payload length stored in key->datalen is also a u16. Use\ncheck_add_overflow() to reject values that do not fit either destination,\nand use kzalloc_flex() for the flexible-array allocation.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98222","source_modified_at":"2026-10-19T09:15:54.199Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"7e70cb4978507cf31d76b90e4cfb4c28cad87f0c","lessThan":"1e720f63dbafc093a8f5d519f05b67724993edd4","status":"affected","versionType":"git"},{"version":"7e70cb4978507cf31d76b90e4cfb4c28cad87f0c","lessThan":"a1a98eca102b1cbbc37ff9eaa197ae4e6a3ea4b0","status":"affected","versionType":"git"},{"version":"7e70cb4978507cf31d76b90e4cfb4c28cad87f0c","lessThan":"cca38f2102a4cd35eda8d48950df4817b4b24757","status":"affected","versionType":"git"},{"version":"7e70cb4978507cf31d76b90e4cfb4c28cad87f0c","lessThan":"8697c431e297eb0d0ab13dda6bc172b48a34f05c","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98222","source_modified_at":"2026-10-19T09:15:54.199Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.38","status":"affected"},{"version":"0","lessThan":"2.6.38","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98222","source_modified_at":"2026-10-19T09:15:54.199Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"1e720f63dbafc093a8f5d519f05b67724993edd4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98222","source_modified_at":"2026-10-19T09:15:54.199Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"8697c431e297eb0d0ab13dda6bc172b48a34f05c","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05743,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:44:57.621Z","modified_at":"2026-10-19T09:15:54.199Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98222","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:15:54.199Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98222","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/1e720f63dbafc093a8f5d519f05b67724993edd4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a1a98eca102b1cbbc37ff9eaa197ae4e6a3ea4b0"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/cca38f2102a4cd35eda8d48950df4817b4b24757"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8697c431e297eb0d0ab13dda6bc172b48a34f05c"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:15:54.199Z","content_hash":"90a2a6041d346328c93de71172cb68e4f4679e7839b975e18f102f5c25dfa8ff"}}
