Description

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 transmission can disrupt the QSPI communication, leading to a denial of service (DoS) where the transfer becomes inoperable.
