CVE-2024-56634

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.74

Description A vulnerability in the Linux kernel has been resolved. The issue is related to the gpio: grgpio component, where the function grgpio probe does not check for a NULL pointer returned by devm kasprintf() in case of an error. This can lead to a kernel NULL pointer dereference error.

Recommendations For Linux kernel versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider adding a NULL check in grgpio probe to handle the kernel NULL pointer dereference error until a patch is available.
