{"id":"AZL-85682","summary":"CVE-2026-35469 affecting package kubernetes for versions less than 1.30.10-23","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.","modified":"2026-08-31T05:26:27Z","published":"2026-04-16T22:16:37Z","upstream":["CVE-2026-35469"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35469"}],"affected":[{"package":{"name":"kubernetes","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kubernetes"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.30.10-23"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-85682.json"}}],"schema_version":"1.9.0"}
