In isotp_continue_receive (receive.c:87-89), the payload_length for a Single Frame is extracted from a 4-bit nibble in the CAN frame data, yielding values 0-15. However, a standard CAN frame is only 8 bytes, with payload starting at data[1] (7 bytes available). When payload_length exceeds the available data (e.g., nibble=15 but only 7 payload bytes exist), memcpy(message.payload, &data[1], payload_length) reads up to 8 bytes past the end of the data buffer."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://gerrit.automotivelinux.org/gerrit/apps/agl-service-can-low-level"},{"url":"https://gist.github.com/sgInnora/8526eedcfd826d05ef1fc45d8f405643"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AC:L/AV:A/A:H/C:L/I:N/PR:N/S:U/UI:N","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":7.1,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-126","lang":"en","description":"CWE-126 Buffer Over-read"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-01T19:33:10.186601Z","id":"CVE-2026-37532","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-01T19:45:17.749Z"}}]},"dataVersion":"5.2"}
