With\nCONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the\nfirst read.\n\nEnlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5\n(\"dm integrity: fix a crash with unusually large tag size\") did for\nintegrity_metadata.\n\nNote that this is not a security bug because the buffer overflow can only\nbe triggered by root.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99098","source_modified_at":"2026-10-26T14:52:04.416Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Linux","vendor":"Linux","versions":[{"version":"fb0987682c629c1d2c476f35f6fde405a5e304a4","lessThan":"3c7aad85aeb9e28386672e3a009aa2e61f751b86","status":"affected","versionType":"git"},{"version":"fb0987682c629c1d2c476f35f6fde405a5e304a4","lessThan":"4f0ee735dc68e3e6c4dd9a666d7f7047163c4165","status":"affected","versionType":"git"},{"version":"fb0987682c629c1d2c476f35f6fde405a5e304a4","lessThan":"f49cd7820cd0a96f20e1aa2708adb002124e38a7","status":"affected","versionType":"git"},{"version":"fb0987682c629c1d2c476f35f6fde405a5e304a4","lessThan":"764b683a6180fd72c931c13fea98d383506a3475","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99098","source_modified_at":"2026-10-26T14:52:04.416Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.114","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.57","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.11","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-2026-99098","source_modified_at":"2026-10-26T14:52:04.416Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"Linux","ecosystem":null},"version":"3c7aad85aeb9e28386672e3a009aa2e61f751b86","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99098","source_modified_at":"2026-10-26T14:52:04.416Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"Linux","ecosystem":null},"version":"4f0ee735dc68e3e6c4dd9a666d7f7047163c4165","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99098","source_modified_at":"2026-10-26T14:52:04.416Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"Linux","ecosystem":null},"version":"764b683a6180fd72c931c13fea98d383506a3475","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T14:52:04.416Z","modified_at":"2026-10-26T14:52:04.416Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99098","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T14:52:04.416Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/3c7aad85aeb9e28386672e3a009aa2e61f751b86"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4f0ee735dc68e3e6c4dd9a666d7f7047163c4165"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f49cd7820cd0a96f20e1aa2708adb002124e38a7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/764b683a6180fd72c931c13fea98d383506a3475"}],"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":"2026-10-26T14:52:04.416Z","content_hash":"3fa6c50f7a901d6eae1885a4615ee094b9e2c479f02561c372b95a3e23fb9cbd"}}
