risc-v reliability

About this tag
The risc-v reliability tag covers discussions about system stability and dependability on RISC-V platforms, with a focus on interrupt handling and kernel-level fixes. A recent thread details CVE-2026-23287, a vulnerability in the SiFive PLIC interrupt controller driver that can cause frozen interrupts due to affinity-setting behavior. This bug, while subtle, can degrade system responsiveness and is difficult to diagnose. The discussion references upstream Linux kernel patches and related documentation, highlighting the importance of reliability in RISC-V hardware and software. Topics include interrupt management, kernel security updates, and platform-specific issues affecting SiFive-based systems.

    CVE-2026-23287 Fix: Prevent Frozen Interrupts in SiFive PLIC IRQ Affinity

    The Linux kernel is once again at the center of a subtle but important reliability fix, and this time the issue sits inside irqchip/sifive-plic, the interrupt-controller driver used on SiFive RISC-V platforms. The vulnerability, identified as CVE-2026-23287, is described as a frozen interrupt...
