Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFC: nci: uart: Set tty-&gt;disc_data only in success path<br /> <br /> Setting tty-&gt;disc_data before opening the NCI device means we need to<br /> clean it up on error paths. This also opens some short window if device<br /> starts sending data, even before NCIUARTSETDRIVER IOCTL succeeded<br /> (broken hardware?). Close the window by exposing tty-&gt;disc_data only on<br /> the success path, when opening of the NCI device and try_module_get()<br /> succeeds.<br /> <br /> The code differs in error path in one aspect: tty-&gt;disc_data won&amp;#39;t be<br /> ever assigned thus NULL-ified. This however should not be relevant<br /> difference, because of "tty-&gt;disc_data=NULL" in nci_uart_tty_open().
