Linux Distros Unpatched Vulnerability : CVE-2026-46148

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - spi: microchip-core-qspi: control built-in cs manually The coreQSPI IP supports only a single chip select, which is automagically operated by the hardware - set...

CVE-2026-46148

A flaw was found in the Linux kernel's microchip-core-qspi driver. When multiple devices are connected to the QSPI controller, the built-in chip select CS was automatically set to an active state even when Linux attempted to access a device using a General Purpose Input/Output GPIO pin for its ch...

CVE-2026-46192

A flaw was found in the Linux kernel's spi: microchip-core-qspi driver. This vulnerability allows the driver to transmit data during emulated read-only dual or quad operations, which are specific modes for communicating with Quad Serial Peripheral Interface QSPI devices. This unintended data...
