Aggregates CVE and security vulnerability intelligence across all cypress-related products, including CVSS, EPSS, publication dates, and vulnerability intelligence data.
Disclosed issues often relate to vendor risk buffer overflow, vendor risk memory corruption, and vendor risk path handling; exposure may include vendor impact application crash in vendor surface software deployment contexts.
| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2023-47415 | Cypress Solutions CTM-200 v2.7.1.5600 and below was discovered to contain an OS command injection vulnerability via the cli_text parameter. | [email protected] | 7.5 | 16.05% | 2024-03-06 | 2026-06-17 |
| CVE-2021-34148 | The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 devices does not properly handle the reception of LMP_max_slot with a greater ACL Length after completion of the LMP setup procedure, allowing attackers in radio range to trigger a denial of service (firmware crash) via a crafted LMP packet. | [email protected] | 6.5 | 0.56% | 2021-09-07 | 2026-06-16 |
| CVE-2021-34147 | The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 does not properly handle the reception of a malformed LMP timing accuracy response followed by multiple reconnections to the link slave, allowing attackers to exhaust device BT resources and eventually trigger a crash via multiple attempts of sending a crafted LMP timing accuracy response followed by a sudden reconnection with a random BDAddress. | [email protected] | 6.5 | 0.56% | 2021-09-07 | 2026-06-16 |
| CVE-2021-34146 | The Bluetooth Classic implementation in the Cypress CYW920735Q60EVB does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service and restart (crash) of the device by flooding it with LMP_AU_Rand packets after the paging procedure. | [email protected] | 6.5 | 0.56% | 2021-09-07 | 2026-06-16 |
| CVE-2021-34145 | The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 devices does not properly handle the reception of LMP_max_slot with an invalid Baseband packet type (and LT_ADDRESS and LT_ADDR) after completion of the LMP setup procedure, allowing attackers in radio range to trigger a denial of service (firmware crash) via a crafted LMP packet. | [email protected] | 5.3 | 0.49% | 2021-09-07 | 2026-06-16 |
| CVE-2019-18614 | On the Cypress CYW20735 evaluation board, any data that exceeds 384 bytes is copied and causes an overflow. This is because the maximum BLOC buffer size for sending and receiving data is set to 384 bytes, but everything else is still configured to the usual size of 1092 (which was used for everything in the previous CYW20719 and later CYW20819 evaluation board). To trigger the overflow, an attacker can either send packets over the air or as unprivileged local user. Over the air, the minimal PoC | [email protected] | 7.8 | 0.34% | 2020-06-16 | 2026-06-16 |
| CVE-2020-11957 | The Bluetooth Low Energy implementation in Cypress PSoC Creator BLE 4.2 component versions before 3.64 generates a random number (Pairing Random) with significantly less entropy than the specified 128 bits during BLE pairing. This is the case for both authenticated and unauthenticated pairing with both LE Secure Connections as well as LE Legacy Pairing. A predictable or brute-forceable random number allows an attacker (in radio range) to perform a MITM attack during BLE pairing. | [email protected] | 7.5 | 0.39% | 2020-06-09 | 2026-06-16 |
| CVE-2019-13916 | An issue was discovered in Cypress (formerly Broadcom) WICED Studio 6.2 CYW20735B1 and CYW20819A1. As a Bluetooth Low Energy (BLE) packet is received, it is copied into a Heap (ThreadX Block) buffer. The buffer allocated in dhmulp_getRxBuffer is four bytes too small to hold the maximum of 255 bytes plus headers. It is possible to corrupt a pointer in the linked list holding the free buffers of the g_mm_BLEDeviceToHostPool Block pool. This pointer can be fully controlled by overflowing with 3 byt | [email protected] | 8.8 | 1.21% | 2020-04-13 | 2026-06-16 |
| CVE-2019-16336 | The Bluetooth Low Energy implementation in Cypress PSoC 4 BLE component 3.61 and earlier processes data channel frames with a payload length larger than the configured link layer maximum RX payload size, which allows attackers (in radio range) to cause a denial of service (crash) via a crafted BLE Link Layer frame. | [email protected] | 6.5 | 1.48% | 2020-02-12 | 2026-06-16 |
| CVE-2019-17061 | The Bluetooth Low Energy (BLE) stack implementation on Cypress PSoC 4 through 3.62 devices does not properly restrict the BLE Link Layer header and executes certain memory contents upon receiving a packet with a Link Layer ID (LLID) equal to zero. This allows attackers within radio range to cause deadlocks, cause anomalous behavior in the BLE state machine, or trigger a buffer overflow via a crafted BLE Link Layer frame. | [email protected] | 6.5 | 0.88% | 2020-02-10 | 2026-06-16 |
| CVE-2018-19860 | Broadcom firmware before summer 2014 on Nexus 5 BCM4335C0 2012-12-11, Raspberry Pi 3 BCM43438A1 2014-06-02, and unspecifed other devices does not properly restrict LMP commnds and executes certain memory contents upon receiving an LMP command, as demonstrated by executing an HCI command. | [email protected] | 8.8 | 1.02% | 2019-06-07 | 2026-06-16 |
| CVE-2007-5922 | The modules/mdop.m in the Cypress 1.0k script for BitchX, as downloaded from a distribution site in November 2007, contains an externally introduced backdoor that e-mails sensitive information (hostnames, usernames, and shell history) to a fixed address. | [email protected] | 5.0 | 1.04% | 2007-11-09 | 2026-06-16 |
