Description OSIDB Bzimport 2026-08-15 06:16:43 UTC 
In the Linux kernel, the following vulnerability has been resolved:

LoongArch: KVM: Validate irqchip index in irqfd routing

Sashiko reported that the irqchip index is not validated for LoongArch.
Add validation and reject out-of-range irqchip indexes to avoid indexing
past the routing table's chip array.
