If an application ended up getting a partial wolfSSL_read() which is sometimes caused by a small user buffer passed in, then called wolfSSL_shutdown for a bidirectional close and attempted to wolfSSL_read() again while the peer continues trying to send data during the shutdown it would lead to a state where a potential heap-use-after free happened.","evidence":"cve:CVE-2026-15442","products":[{"name":{"value":"wolfSSL","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"low","structured":{"id":"CVE-2026-15442","aliases":["CVE-2026-15442"],"metrics":[{"format":"CVSS","cvssV4_0":{"Safety":"NOT_DEFINED","version":"4.0","Recovery":"NOT_DEFINED","baseScore":2.3,"Automatable":"NOT_DEFINED","attackVector":"NETWORK","baseSeverity":"LOW","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","exploitMaturity":"NOT_DEFINED","providerUrgency":"NOT_DEFINED","userInteraction":"NONE","attackComplexity":"HIGH","attackRequirements":"PRESENT","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"LOW","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"NONE","vulnerabilityResponseEffort":"NOT_DEFINED"},"scenarios":[{"lang":"en","value":"GENERAL"}]}],"affected":[{"vendor":"wolfSSL","product":"wolfSSL","versions":[{"status":"affected","version":"4.4.0","versionType":"semver","lessThanOrEqual":"5.9.2"}],"defaultStatus":"unaffected"}],"modified":"2026-09-30T10:48:05.055Z","provider":"cve","references":["https://github.com/wolfSSL/wolfssl/pull/10863"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-15442","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-30T10:47:12.677039Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-30T10:48:05.055Z"}}],"cna":{"orgId":"50d2cd11-d01a-48ed-9441-5bfce9d63b27","shortName":"wolfSSL","dateUpdated":"2026-09-27T09:24:31.594Z"}}},"related_cves":[{"value":"CVE-2026-15442","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":4175,"next_before":4175}
