Linux kernel IRQ chip driver DoS

The vulnerability in the plicirqdisable function within the drivers/irqchip/irq-sifive-plic.c file of the Linux kernel’s IRQ chip driver is related to a race condition during resource copying. Exploitation of this vulnerability may allow an attacker to cause a denial of service...

EUVD-2026-15215

In the Linux kernel, the following vulnerability has been resolved: irqchip/sifive-plic: Fix frozen interrupt due to affinity setting PLIC ignores interrupt completion message for disabled interrupt, explained by the specification: The PLIC signals it has completed executing an interrupt handler ...

CVE-2026-23287

A flaw was found in the Linux kernel's irqchip/sifive-plic component. When an interrupt's affinity setting is changed while a hardware thread hart is still processing the interrupt, the Programmable Interrupt Controller PLIC may ignore the interrupt completion message. This can lead to the...

CVE-2026-23287

The CVE-2026-23287 issue affects the Linux kernel’s PLIC interrupt handling for SiFive irqchip, where a race between affinity changes and interrupt enable bits could freeze an interrupt. Root cause: completion handling could ignore or mis-handle an interrupt if the hart affinity change left the e...
