cve-2026-46148

CVE-2026-46148 is a Linux kernel vulnerability in the Microchip coreQSPI SPI controller driver, published by NVD on May 28, 2026. The bug allows the controller's built-in chip select to be asserted while Linux communicates with another SPI device, potentially causing data corruption or unintended device access. This hardware-specific issue is narrow and still awaiting NVD enrichment, but it highlights a critical boundary between software policy and hardware automation. For administrators managing embedded Linux systems, industrial appliances, or edge devices, this vulnerability serves as a reminder that subtle electrical assumptions in drivers can lead to security or reliability failures. Discussions on WindowsForum cover the technical details and implications for Linux-based systems.
