Description:
 An issue was discovered in the Linux kernel before 5.4.17.
 drivers/spi/spi-dw.c allows attackers to cause a panic via concurrent calls
 to dw_spi_irq and dw_spi_transfer_one, aka CID-19b61392c5a8.
Ubuntu-Description:
 It was discovered that the DesignWare SPI controller driver in the Linux
 kernel contained a race condition. A local attacker could possibly use this
 to cause a denial of service (system crash).
