CVE-2024-36890

In the Linux kernel, the following vulnerability has been resolved:
mm/slab: make __free(kfree) accept error pointers Currently, if an
automatically freed allocation is an error pointer that will lead to a
crash. An example of this is in wm831x_gpio_dbg_show(). 171 char *label
__free(kfree) = gpiochip_dup_line_label(chip, i); 172 if (IS_ERR(label)) {
173 dev_err(wm831x->dev, “Failed to duplicate label\n”); 174 continue; 175
} The auto clean up function should check for error pointers as well,
otherwise we’re going to keep hitting issues like this.
