Broadcom Bluetooth firmware version 2.2.3.593 is typically associated with a driver package (often version 2.2.3.593.596a) released for Windows 7 systems, specifically for Sony VAIO hardware. Key Details for Version 2.2.3.593
Target Hardware: Broadcom Bluetooth controllers often integrated into Sony VAIO laptops (e.g., VPCB11NGX).
Operating System: Primarily optimized for Windows 7 (64-bit), though it may function on other legacy Windows versions.
Functionality: This update provides the necessary firmware "blobs" required for the operating system to initialize and manage the Bluetooth hardware properly. How to Update or Install
Broadcom has transitioned its consumer driver support directly to Microsoft’s Windows Update service. Automatic Update: Open Device Manager.
Find your Bluetooth adapter under "Bluetooth" or "Network Adapters." bluetooth firmware -broadcom- update version 2.2.3.593
Right-click it and select Update driver > Search automatically for updated driver software. Manual Installation:
If Windows Update does not find the driver, you can find legacy versions on Softpedia or the Sony Support site by searching for your specific laptop model. For Linux Users:
Firmware for Broadcom chipsets (like BCM20702 or BCM43142) often needs to be manually placed in /lib/firmware/brcm/. You can find the required .hcd files in community repositories like the winterheart/broadcom-bt-firmware GitHub.
Note on Security: As Broadcom has ended active support for many older consumer devices, these legacy firmware versions may not contain fixes for more recent Bluetooth vulnerabilities.

This paper provides an in-depth examination of Broadcom Bluetooth firmware update version 2.2.3.593, a patch historically distributed via Windows Update and OEM support channels. While superficially a minor revision increment, this update addresses critical vulnerabilities in the Bluetooth stack, improves power management in Broadcom BCM43xx and BCM2070 series chipsets, and resolves coexistence issues with 2.4 GHz Wi-Fi radios. The paper explores the technical architecture of Broadcom Bluetooth firmware, the specific remediated vulnerabilities (including CVE-2017-0781 and Bluetooth Impersonation attacks), performance benchmarks, and deployment best practices.
Before dissecting version 2.2.3.593, it’s crucial to understand the distinction between a driver and firmware.
Broadcom (now owned by Cypress Semiconductor, then Infineon) produces some of the most common Bluetooth radio chips on the market, including the BCM2070, BCM43142, BCM94352, and BCM20702 series. These chips often appear in Dell, HP, Lenovo, and Acer laptops.
The firmware version 2.2.3.593 is a specific patch for Broadcom’s RAM-USB and UART Bluetooth devices, primarily distributed through Windows Update’s driver catalog or OEM support sites. Abstract This paper provides an in-depth examination of
Even a successful update to version 2.2.3.593 can cause side effects. Here is what to do if things go wrong.
While the full BIAS attack (CVE-2020-10135) was disclosed later, retrospect analysis shows 2.2.3.593 introduced early hardening: stricter role-switch authentication and rejection of legacy authentication without encryption during Secure Simple Pairing (SSP) mode.
Firmware version 2.2.3.593 is not universal. It specifically targets Broadcom Bluetooth chips with a hardware ID (VID/PID) that matches certain ranges. You can check your device via Device Manager (Windows):
Win + X and select Device Manager.If you see values like:
USB\VID_0A5C&PID_21E8USB\VID_0A5C&PID_21ECUSB\VID_0A5C&PID_216F...then version 2.2.3.593 is likely intended for your chip.
