CVE-2026-93274
Sumário
de MITRE • 24/09/2026
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: bcm2835: Don't remove an unregistered GPIO chip
If the devm_pinctrl_register() function fails, bcm2835_pinctrl_probe() calls gpiochip_remove() before gpiochip_add_data() has registered the GPIO chip.
This means that upon failure the gpio_chip.gpiodev is NULL resulting in a null pointer dereference inside the gpiochip_remove() function.
Remove the unnecessary function call to gpiochip_remove(). No GPIO cleanup is required because the GPIO chip has not yet been registered. Without this change there is potential for a kernel panic upon registration failure
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
