Its hci parsing software dynamically determines the length of certain hci packets by reading a byte from its header. This value is assumed to be greater than or equal to 3, but the software doesn't ensure that this is the case. Supplying a length less than 3 leads to a buffer overflow in a buffer that is allocated later. It is simultaneously possible to cause another integer overflow by supplying large length values because the provided length value is increased by a few bytes to account for additional information that is supposed to be stored there. This bug is trivial to exploit for a denial of service but is not certain to suffice to bring the system down and can generally not be exploited further because the exploitable buffer is dynamically allocated."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/mbed-ce/mbed-os/blob/54e8693ef4ff7e025018094f290a1d5cf380941f/connectivity/FEATURE_BLE/libraries/cordio_stack/ble-host/sources/hci/dual_chip/hci_evt.c#L2748"},{"url":"https://github.com/mbed-ce/mbed-os/pull/386"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-120","lang":"en","description":"CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')"}]}],"affected":[{"vendor":"mbed","product":"mbed","cpes":["cpe:2.3:o:mbed:mbed:6.16.0:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"6.16.0","status":"affected"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-11-25T21:03:34.891859Z","id":"CVE-2024-48982","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"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":"2024-11-25T21:03:47.200Z"}}]},"dataVersion":"5.1"}
