|---|---|---|---|---|---|---|
| CVE-2024-48984 | An issue was discovered in MBed OS 6.16.0. When parsing hci reports, the hci parsing software dynamically determines the length of a list of reports by reading a byte from an input stream. It then fetches the length of the first report, uses it to calculate the beginning of the second report, etc. In doing this, it tracks the largest report so it can later allocate a buffer that fits every individual report (but only one at a time). It does not, however, validate that these addresses are all con | [email protected] | 9.8 | 0.81% | 2024-11-20 | 2025-09-24 |
| CVE-2024-22905 | Buffer Overflow vulnerability in ARM mbed-os v.6.17.0 allows a remote attacker to execute arbitrary code via a crafted script to the hciTrSerialRxIncoming function. | [email protected] | 7.0 | 4.10% | 2024-04-19 | 2025-09-15 |
| CVE-2020-12886 | A buffer over-read was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse() parses the CoAP packet header starting from the message token. The length of the token in the received message is provided in the first byte parsed by the sn_coap_parser_options_parse() function. The length encoded in the message is not validated against the actual input buffer length before accessing the token. | [email protected] | 9.1 | 0.56% | 2020-06-18 | 2024-11-21 |
| CVE-2020-12885 | An infinite loop was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse_multiple_options() parses CoAP options in a while loop. This loop's exit condition is computed using the previously allocated heap memory required for storing the result of parsing multiple options. If the input heap memory calculation results in zero bytes, the loop exit condition is never met and the loop is not t | [email protected] | 7.5 | 0.38% | 2020-06-18 | 2024-11-21 |
| CVE-2020-12884 | A buffer over-read was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse_multiple_options() parses CoAP options that may occur multiple consecutive times in a single packet. While processing the options, packet_data_pptr is accessed after being incremented by option_len without a prior out-of-bounds memory check. The temp_parsed_uri_query_ptr is validated for a correct range, but the r | [email protected] | 9.1 | 0.56% | 2020-06-18 | 2024-11-21 |
| CVE-2020-12883 | Buffer over-reads were discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse() parses CoAP input linearly using a while loop. Once an option is parsed in a loop, the current point (*packet_data_pptr) is increased correspondingly. The pointer is restricted by the size of the received buffer, as well as by the option delta and option length bytes. The actual input packet length is not verifi | [email protected] | 9.1 | 0.82% | 2020-06-18 | 2024-11-21 |
