{"schema":"threatline.record/2","record":{"id":"CVE-2026-97907","aliases":[],"summary":"Bluetooth: btrtl: Don't leak return code when parsing firmware format v2","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btrtl: Don't leak return code when parsing firmware format v2\n\nWhen key_id from chip is zero, rtlbt_parse_firmware_v2() intentionally\nignores all security headers. However, the implementation simply breaks\nfrom a switch statement and leaks uninitialized return code `rc' (if the\nfirst section is a security one) or the previous section's `rc'.\n\nFix it by really skipping a loop with `continue'. For consistency and\nreadability, also do the same for the default case.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97907","source_modified_at":"2026-10-19T09:10:33.668Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"9a24ce5e29b15c4c6b0c89c04f9df6ce14addefa","lessThan":"ba96047bba4a6101267cf4f6b3057cbc58e6c554","status":"affected","versionType":"git"},{"version":"9a24ce5e29b15c4c6b0c89c04f9df6ce14addefa","lessThan":"90f3a142b5f8596a565b8e080d18a8050be6edef","status":"affected","versionType":"git"},{"version":"9a24ce5e29b15c4c6b0c89c04f9df6ce14addefa","lessThan":"422f6547259654bae690713614c794dd1e2c0a0b","status":"affected","versionType":"git"},{"version":"9a24ce5e29b15c4c6b0c89c04f9df6ce14addefa","lessThan":"c4249cf6e80b1bd62a6a409aaabe760fe025dac3","status":"affected","versionType":"git"},{"version":"9a24ce5e29b15c4c6b0c89c04f9df6ce14addefa","lessThan":"83e3e515fd261600ed8491fb0a8bcdfb115c904e","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97907","source_modified_at":"2026-10-19T09:10:33.668Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","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-2026-97907","source_modified_at":"2026-10-19T09:10:33.668Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"90f3a142b5f8596a565b8e080d18a8050be6edef","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97907","source_modified_at":"2026-10-19T09:10:33.668Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"422f6547259654bae690713614c794dd1e2c0a0b","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97907","source_modified_at":"2026-10-19T09:10:33.668Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"83e3e515fd261600ed8491fb0a8bcdfb115c904e","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.0933,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:22:32.244Z","modified_at":"2026-10-19T09:10:33.668Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97907","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:10:33.668Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97907","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/ba96047bba4a6101267cf4f6b3057cbc58e6c554"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/90f3a142b5f8596a565b8e080d18a8050be6edef"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/422f6547259654bae690713614c794dd1e2c0a0b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c4249cf6e80b1bd62a6a409aaabe760fe025dac3"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/83e3e515fd261600ed8491fb0a8bcdfb115c904e"}],"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":"2026-10-19T09:10:33.668Z","content_hash":"f0bcdebb838738c8afd165b5dd7162c72a7dbb6e77b1da259742d1221a1fc3ca"}}
