Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/slab: make __free(kfree) accept error pointers<br /> <br /> Currently, if an automatically freed allocation is an error pointer that<br /> will lead to a crash. An example of this is in wm831x_gpio_dbg_show().<br /> <br /> 171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i);<br /> 172 if (IS_ERR(label)) {<br /> 173 dev_err(wm831x-&gt;dev, "Failed to duplicate label\n");<br /> 174 continue;<br /> 175 }<br /> <br /> The auto clean up function should check for error pointers as well,<br /> otherwise we&amp;#39;re going to keep hitting issues like this.
