CVE-2022-49722

CVE-2022-49722 concerns memory corruption in the Linux kernel’s ice VF (virtual function) driver. The issue occurs when a VF’s RX/TX queues are not correctly disabled after a reset, allowing DMA resources to remain unmapped while queues are active, which can lead the device to map packets to memo...
