Description

A flaw was found in the Linux kernel's meson-spicc Serial Peripheral Interface (SPI) controller driver. This vulnerability occurs due to a double-put operation when removing the controller, where the spi_controller_put() function is called redundantly. This can lead to memory corruption, potentially causing a system crash and resulting in a Denial of Service (DoS).
