It is a use-after-free caused by QUICHE continuing push request headers after `StopReading()` being called on the stream. As after `StopReading()`, the HCM's `ActiveStream` might have already be destroyed and any up calls from QUICHE could potentially cause use after free.","epss":{"date":"2026-11-05","percentile":0.53061,"score":0.00693},"exploits":[{"kind":"exploit","source":"security-advisories@github.com","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"},{"kind":"exploit","source":"af854a3a-2127-422b-91ae-364da2661108","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"}],"kev":null,"metrics":[{"score":5.9,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":7.5,"severity":"high","source":"NVD: nvd@nist.gov","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":5.9,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793895433163,"publishedAt":1717534807788,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"},{"source":"ADP: CVE","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"},{"source":"security-advisories@github.com","tags":["Exploit","Third Party Advisory"],"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"},{"source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Third Party Advisory"],"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-mgxp-7hhp-8299"}],"remediation":[],"revision":"8b82546bf7b1b17121c9f14f0d0a17cf3f7c3d783d9fa79af3923f4b5aaabcf4","sources":[{"modifiedAt":1793894110919,"name":"CNA: GitHub_M","retrievedAt":1793895164826,"url":"https://www.cve.org/CVERecord?id=CVE-2024-32974"},{"modifiedAt":1793895433163,"name":"NVD","retrievedAt":1793902563886,"url":"https://nvd.nist.gov/vuln/detail/CVE-2024-32974"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793895193245,"url":"https://api.first.org/data/v1/epss?cve=CVE-2024-32974"}],"ssvc":{"assessedAt":1721413805375,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Envoy affected by a crash in EnvoyQuicServerStream::OnInitialHeadersComplete()","updatedAt":1793902563886}
