embedded security

About this tag
Embedded security on WindowsForum.com covers vulnerabilities and fixes in low-level firmware and bootloader components that underpin embedded systems, including Linux kernel drivers, U-Boot, and cryptographic libraries like wolfSSL. Recent discussions detail CVEs in Microchip PolarFire SoC clock drivers, Renesas SPI controllers, and DesignWare SPI DMA paths, as well as critical U-Boot flaws in NFS, DHCP, and memory access control affecting Qualcomm IPQ devices. A timing side-channel in wolfSSL highlights compiler-induced risks. These threads emphasize that embedded security extends beyond desktop Windows to the firmware and kernel code running on routers, industrial controllers, and IoT devices, where narrow bugs can have outsized impact on system integrity and supply chain trust.

  1. CVE-2026-46293: Microchip PolarFire Linux Clock Driver OOB Fix Explained

    CVE-2026-46293 is a newly published Linux kernel vulnerability, added to NVD on June 8, 2026, covering an out-of-bounds access in the Microchip PolarFire SoC fabric clock driver during registration of clock outputs. The bug is not the kind of headline-grabbing flaw that sends Windows desktop...

  2. CVE-2026-46225: Linux spi-rspi Teardown Order Fix for Renesas RSPI/QSPI

    CVE-2026-46225, published by NVD on May 28, 2026, is a newly assigned Linux kernel vulnerability in the Renesas RSPI/QSPI SPI controller driver, fixed by changing driver teardown so the SPI controller is deregistered before DMA and other backing resources are released. The vulnerability is still...

  3. CVE-2026-31560: Linux SPI DMA Crash Caused by Faulty Error Logging

    CVE-2026-31560 is a small Linux kernel fix with an outsized lesson: sometimes the crash is not in the failed hardware transaction, but in the error log that tries to describe it. The flaw sits in the DesignWare SPI DMA path, where a timeout or error could leave the driver without a current SPI...

    Das U-Boot's DHCP code contains a subtle but dangerous buffer overread that has been tracked as CVE-2024-42040: an attacker on the local or adjacent network can feed crafted DHCP responses that cause net/bootp.c to copy memory beyond the received packet, leaking between 4 and 32 bytes of host...

  7. CVE-2025-13912: WolfSSL Timing Side Channel Fixed in 5.8.4

    CVE-2025-13912 is a timing‑side‑channel concern in wolfSSL where compiler optimizations (notably from Clang/LLVM toolchains) can transform carefully written constant‑time C code into binaries whose runtime varies with secret data — a behavior that undermines cryptographic assumptions and was...
