AI-suggested
A patch is available that fixes the issue by initializing the s32_pinctrl_desc structure with zeroed memory using devm_kzalloc() instead of devm_kmalloc(). Users should apply the official Linux kernel updates that include this fix. The Ubuntu advisory USN-8094-1 confirms the availability of this fix.
Description
A vulnerability in the Linux kernel's pinctrl subsystem for the s32cc platform caused uninitialized memory usage in the s32_pinctrl_desc structure. This led to intermittent allocation errors and failures in parsing device tree node properties, impacting dependent drivers such as I2C adapters. The issue was fixed by initializing the structure with zeroed memory using devm_kzalloc() instead of devm_kmalloc().
