Name of the Vulnerable Software and Affected Versions Linux kernel versions through 5.3.11

Description A memory leak in the spi gpio probe() function in drivers/spi/spi-gpio.c allows attackers to cause a denial of service by triggering devm add action or reset() failures. This issue is disputed by third parties because the system must have already been out of memory before the probe began.

Recommendations For Linux kernel versions through 5.3.11, update to a version later than 5.3.11 to resolve the issue. As a temporary workaround, consider restricting system resources to prevent memory exhaustion.
