{"schema":"threatline.record/2","record":{"id":"CVE-2026-97565","aliases":[],"summary":"smb: client: reject short READ responses in CIFSSMBRead()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: reject short READ responses in CIFSSMBRead()\n\nCIFSSMBRead() reads DataLengthHigh, DataLength and DataOffset out of\nthe READ_RSP returned by the server without first checking that a\nwhole READ_RSP was actually received. The length of the response is\nrecorded in rsp_iov.iov_len, but nothing constrains it to be at least\nread_rsp_size before those fields are dereferenced.\n\nA malicious or compromised SMB1 server can return a response shorter\nthan the READ_RSP header, so that parsing the header itself reads past\nthe end of the receive buffer. SMB1 is not negotiated by default;\nreaching this code requires an explicit vers=1.0 mount.\n\nReject the response unless it is at least read_rsp_size bytes long.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97565","source_modified_at":"2026-10-19T09:09:28.115Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"0f1f77b821506a4dacab6ce7d29cf9e0c26f14cd","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"aaa221c1b1d288845b55e9c366e5ef608dfff49d","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"e6142a8bfc230c7263eb8b0475249c958ce49367","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97565","source_modified_at":"2026-10-19T09:09:28.115Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","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-2026-97565","source_modified_at":"2026-10-19T09:09:28.115Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"0f1f77b821506a4dacab6ce7d29cf9e0c26f14cd","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00198,"percentile":0.09053,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:52.459Z","modified_at":"2026-10-19T09:09:28.115Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97565","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:09:28.115Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97565","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/0f1f77b821506a4dacab6ce7d29cf9e0c26f14cd"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/aaa221c1b1d288845b55e9c366e5ef608dfff49d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e6142a8bfc230c7263eb8b0475249c958ce49367"}],"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":"2026-10-19T09:09:28.115Z","content_hash":"6863750041c2ff830138c43b7ab4d76deeec766f89db0d354f80f28ecd2a3ff7"}}
