CyberRota Analysis
AI-GeneratedA vulnerability exists in the Linux kernel affecting the LoongArch architecture, where the irqchip index is not properly validated during irqfd routing. This oversight could allow an attacker to exploit out-of-range irqchip indexes, potentially leading to system instability or unauthorized access. Linux system administrators and developers working with LoongArch should prioritize addressing this issue to mitigate risks associated with improper irqchip handling.
Original NVD Description
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.
