About this tag
The riscv tag on WindowsForum.com covers Linux kernel security vulnerabilities and fixes specific to the RISC-V architecture. Recent discussions include CVE-2026-23217, a deadlock in the kernel's ftrace when instrumenting SBI ecall functions on RISC-V systems, resolved by build-time exclusion. CVE-2024-26902 involves a NULL pointer dereference in the RISC-V PMU overflow handler that can cause kernel panics, with Microsoft's advisory noting potential impact on Azure Linux. CVE-2025-40079 addresses a BPF sign-extension bug on RISC-V that could lead to kernel panics, fixed by a patch ensuring proper ABI compliance. These threads highlight ongoing efforts to harden the RISC-V Linux kernel against crashes and denial-of-service conditions.

    Microsoft Magnetar zkVM: Hash-Based Post-Quantum Proofs for Rust, Go and C

    Every piece of software output in the modern enterprise carries an invisible asterisk: do you actually trust the machine—and the organization—that produced it? Today, IT administrators, security architects, and compliance teams bridge that gap using service-level agreements, audit logs, and...

    Russia’s ME26 Retro Gaming Demos Showcase Baikal RISC-V, Arm Hypercom-U and Elbrus PCs

    When hardware engineers want to prove that a piece of silicon can actually boot, push pixels, and handle real-time user input without catching fire, they rarely reach for an enterprise spreadsheet. They reach for classic video games. At the Microelectronics 26 (ME26) industry forum in Sochi...

    Nuvacore WarpCore: Ex-Nuvia Team Builds CPU Core Before Choosing Arm, x86 or RISC-V

    Most CPU projects start with the instruction set. Nuvacore says it is starting with the core. The startup comes from the same architects whose last company, Nuvia, ended up shaping Qualcomm's Snapdragon X Elite chips for Windows on Arm laptops. It has now given its first real description of how...

    Nvidia GSP Makes RTX Driver Updates Firmware-Dependent

    Nvidia’s GPU System Processor, or GSP, has moved a substantial slice of low-level GPU management out of the host-side graphics driver and onto RISC-V cores inside the GPU itself. That is the practical finding behind XDA Developers’ examination of Nvidia firmware and open kernel-module code, and...

    Karnataka KEO Rollout Plans 2,222 Offline AI Learning PCs

    Karnataka is preparing to place 2,222 KEO AI-capable computers in rural learning centres and residential schools, betting that local processing and preloaded course material can make basic AI-assisted study useful where broadband is unreliable. The important detail is not the “AI PC” label: KEO...

    CVE-2026-23217: RISC-V Linux Kernel Ftrace Deadlock Fixed by Build Time Exclusion

    A newly assigned Linux kernel vulnerability, CVE-2026-23217, exposes a subtle but serious deadlock risk on RISC‑V systems when the kernel’s function tracer (ftrace) is configured to snapshot SBI ecall functions — a situation that can hang the entire system. The fix merged into the kernel trees...

    CVE-2024-26902: Linux RISCV PMU Panic and Azure Linux Attestation

    CVE-2024-26902 exposes a narrowly scoped but real risk in the Linux kernel’s RISC‑V performance monitoring path: a coding error in the PMU overflow handler can, under specific conditions, trigger a NULL pointer dereference and kernel panic. Microsoft’s published advisory for this CVE calls out...

    Linux Kernel Patch Fixes RISC-V BPF Sign Extension for CVE-2025-40079

    The Linux kernel received a focused upstream fix for CVE-2025-40079 — a RISC‑V specific BPF correctness bug where struct ops return values were not being sign‑extended according to the RISC‑V ABI, a mismatch that could trigger kernel panics in the ns_bpf_qdisc selftest and destabilize hosts...
