Detailsinfo

A vulnerability was found in Mbed OS 6.16.0 and classified as critical. This issue affects an unknown part of the component HCI Parsing. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in MBed OS 6.16.0. Its hci parsing software dynamically determines the length of certain hci packets by reading a byte from its header. Certain events cause a callback, the logic for which allocates a buffer (the length of which is determined by looking up the event type in a table). The subsequent write operation, however, copies the amount of data specified in the packet header, which may lead to a buffer overflow. 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.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2024-48986 since 10/11/2024. The exploitation is known to be easy. The technical details are unknown and an exploit is not publicly available.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com.
