{"id":"CVE-2026-35469","summary":"SpdyStream: DOS on CRI","details":"spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes — all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1.","aliases":["GHSA-pc3f-x583-g7j2"],"modified":"2026-04-18T04:19:15.166213Z","published":"2026-04-16T21:19:23.516Z","related":["CGA-v7gj-rrxh-8985"],"database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35469.json","cwe_ids":["CWE-770"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35469.json"},{"type":"WEB","url":"https://github.com/moby/spdystream/releases/tag/v0.5.1"},{"type":"ADVISORY","url":"https://github.com/moby/spdystream/security/advisories/GHSA-pc3f-x583-g7j2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35469"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/moby/spdystream","events":[{"introduced":"0"},{"fixed":"c59e5d73daa301bde452ea77545bdf51e32554a2"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"0.5.1"}]}}],"versions":["v0.1.0","v0.2.0","v0.3.0","v0.4.0","v0.5.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-35469.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
