Last modified Jun 17, 2026

CVE-2019-19070 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A memory leak in the spi_gpio_probe() function in drivers/spi/spi-gpio.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering devm_add_action_or_reset() failures, aka CID-d3b0ffa1d75d. NOTE: third parties dispute the relevance of this because the system must have already been out of memory before the probe began. EPSS estimates a 2.85% chance of exploitation in the next 30 days.
