In versions 0.5.0 and earlier, the SPDY/3 frame parser reads 32\u2011bit counts and lengths supplied by the remote peer and uses them directly as allocation sizes, without performing bounds checking. Because SPDY header blocks are zlib\u2011compressed, an attacker can send a small on\u2011the\u2011wire frame that decompresses into a much larger value, causing the library to allocate excessive memory. A single crafted frame can exhaust process memory and trigger an out\u2011of\u2011memory crash. This is a resource\u2011exhaustion vulnerability identified as CWE\u2011770.", "risk_and_exploitability": "The CVSS score of 8.7 indicates high severity, while no EPSS score is available, making the exact likelihood of exploitation uncertain but not negligible. The vulnerability is not listed in the CISA KEV catalog. Attackers can trigger the denial of service by sending a single malicious SPDY frame to any service that uses spdystream, such as container runtimes or other components that multiplex streams over SPDY. The resulting out\u2011of\u2011memory crash can lead to service interruption and potential cascading effects on dependent workloads."}}}}, "created": "2026-04-16T09:00:05.304120+00:00", "updated": "2026-04-17T03:00:08.439913+00:00", "vendors": ["kubernetes", "kubernetes$PRODUCT$kubelet"]}
