Summary
CVE-2024-56634 is a newly identified vulnerability in the Linux kernel. This issue lies in the gpio subsystem's grgpio driver, specifically in the grgpio_probe function. devm_kasprintf() is utilized in this function to allocate memory, but it can return a NULL pointer upon failure. However, the returned value is not checked for NULL, potentially leading to a kernel pointer dereference error. This vulnerability has been resolved with the addition of a NULL check in grgpio_probe to prevent such errors.
