In the Linux kernel, the following vulnerability has been resolved:

gpio: mvebu: fix NULL pointer dereference in suspend/resume

mvebu_pwm_suspend() and mvebu_pwm_resume() are called for all GPIO banks during suspend/resume, but not all banks have PWM functionality. GPIO banks without PWM have mvchip->mvpwm set to NULL.

Calling mvebu_pwm_suspend() with mvpwm == NULL causes a NULL pointer dereference when it tries to access mvpwm->blink_select.
