CVE-2020-12769

Published: 9 May 2020

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.

From the Ubuntu security team

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).
