CVE-2026-46148

In the Linux kernel, the following vulnerability has been resolved: 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 low when the transmit buffer first gets written to and set high when...

CVE-2026-46148

CVE-2026-46148 concerns the Linux kernel’s microchip-core-qspi driver where the built-in chip select could be driven active when multiple devices share the QSPI controller, potentially conflicting with GPIO-based CS. The provided records confirm a concrete fix: the driver now controls chip select...
