Summary
Fix high severity security issue in
modules/py32ioexp-1.0/py32ioexp.c.Vulnerability
V-006modules/py32ioexp-1.0/py32ioexp.c:373Description: The py32io_gpio_direction_input() function accepts an unsigned offset parameter representing a GPIO pin number. If this offset is not validated against chip->ngpio before being used to index into internal arrays or I2C register maps, an out-of-bounds read or write can occur. A local user with access to the GPIO character device (/dev/gpiochipN) or sysfs GPIO interface can supply an out-of-range offset value to trigger this condition.
