What is CVE-2024-48982?

In MBed OS version 6.16.0, a vulnerability exists in the hci parsing software that improperly assumes the length of certain hci packets will always be three bytes or greater. When a packet length less than three is supplied, it triggers a buffer overflow due to insufficient validation of the packet length. Additionally, the vulnerability allows for an integer overflow by supplying excessively large length values, as the system increases the received length for accounting additional data. This flaw can be easily exploited for denial of service purposes, although it does not definitively lead to a complete system failure. Furthermore, the dynamically allocated buffer limits the extent of potential exploitation.
