Cybersecurity researchers have discovered 11 old, Microsoft-signed, Unified Extensible Firmware Interface (UEFI) applications that could be abused to bypass Secure Boot on most systems using the modern firmware standard

Six vulnerabilities in the widely used U-Boot bootloader have been discovered that could allow attackers to execute malicious code during device boot, potentially enabling stealthy firmware attacks that compromise security protections and install persistent malware. [...]

Unauthenticated Flaw Allows Full Router, Network TakeoverA hidden backdoor, disclosed by CERT/CC and found in multiple firmware versions made by Chinese manufacturer Tenda, bypasses authentication and could grant attackers administrative access. Researchers are reporting exploitation and an Nmap script is making vulnerable devices easier to identify.

Researchers are reporting exploitation and an Nmap script is making vulnerable devices easier to identify.

Several versions of firmware released by Chinese network device manufacturer Tenda have been found to embed an undocumented authentication backdoor that enables administrative access to the devices' web management interfaces, the CERT Coordination Center (CERT/CC) warned Monday

Security firm runZero has disclosed seven vulnerabilities in FatFs, a small filesystem library that lets a device read and write the FAT and exFAT formats used on USB drives and SD cards

Google has announced the integration of a Rust-based Domain Name System (DNS) parser into the modem firmware as part of its ongoing efforts to beef up the security of Pixel devices and push memory-safe code at a more foundational level

TP-Link has patched several vulnerabilities in its Archer NX router series, including a critical-severity flaw that may allow attackers to bypass authentication and upload new firmware. [...]

Internet-Connected Remote Access Tools Operate at UEFI LevelA flood of lost-cost devices for remote IP control of servers or human-machine interfaces has roused a concomitant wave of security warnings about their security defects. Firmware security company Eclypsium probed devices made by four KVM vendors, discovering nine vulnerabilities.

Texas sued networking giant TP-Link Systems, accusing the company of deceptively marketing its routers as secure while allowing Chinese state-backed hackers to exploit firmware vulnerabilities and access users' devices. [...]

State disputes the company's claim that its routers are made in Vietnam TP-Link is facing legal action from the state of Texas for allegedly misleading consumers with "Made in Vietnam" claims despite China-dominated manufacturing and supply chains, and for marketing its devices as secure despite reported firmware vulnerabilities exploited by Chinese state-sponsored actors.…

Fortinet has confirmed a new, actively exploited critical FortiCloud single sign-on (SSO) authentication bypass vulnerability, tracked as CVE-2026-24858, and says it has mitigated the zero-day attacks by blocking FortiCloud SSO connections from devices running vulnerable firmware versions. [...]

Fix landed in July, but OEM firmware updates are required If you use virtual machines, there's reason to feel less-than-Zen about AMD's CPUs. Computer scientists affiliated with the CISPA Helmholtz Center for Information Security in Germany have found a vulnerability in AMD CPUs that exposes secrets in its secure virtualization environment.…

The UEFI firmware implementation in some motherboards from ASUS, Gigabyte, MSI, and ASRock is vulnerable to direct memory access (DMA) attacks that can bypass early-boot memory protections. [...]

Certain motherboard models from vendors like ASRock, ASUSTeK Computer, GIGABYTE, and MSI are affected by a security vulnerability that leaves them susceptible to early-boot direct memory access (DMA) attacks across architectures that implement a Unified Extensible Firmware Interface (UEFI) and input–output memory management unit (IOMMU)

ASUS has released new firmware to patch nine security vulnerabilities, including a critical authentication bypass flaw in routers with AiCloud enabled. [...]

TP-Link has made firmware updates available for a broad range of Omada gateway models to address four vulnerabilities, among which a critical pre-auth OS command injection. [...]
