Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.x

Description The issue is related to the Goodix gt915 touchscreen driver, where the goodix tool.c file does not properly synchronize updates to a global variable. This allows local users to bypass intended access restrictions or cause a denial of service, resulting in memory corruption, via crafted arguments to the procfs write handler.

Recommendations For Linux kernel version 3.x, consider applying a patch that properly synchronizes updates to the global variable in the goodix tool.c file to prevent local users from bypassing access restrictions or causing a denial of service.
