AI-suggested
A patch is available and should be applied to affected Linux kernel versions to correct the NULL pointer check in spacemit_pin_set_config(). Applying the official fix restores proper pin configuration and prevents potential NULL pointer dereference.
Description
A vulnerability in the Linux kernel's pinctrl subsystem (spacemit driver) was fixed by correcting a NULL pointer check in the spacemit_pin_set_config function. The function incorrectly checked the pin ID variable instead of the pointer returned by spacemit_get_pin(), causing the configuration for pin 0 to be skipped. This could lead to silent failure in configuring the drive-strength and bias settings for the first pin of every group on affected hardware such as K3 Pico-ITX. The fix ensures proper PAD setup for pin 0 and prevents potential NULL pointer dereference.
