"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: pn533: Add poll mod list filling check\n\nIn case of im_protocols value is 1 and tm_protocols value is 0 this\ncombination successfully passes the check\n'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().\nBut then after pn533_poll_create_mod_list() call in pn533_start_poll()\npoll mod list will remain empty and dev->poll_mod_count will remain 0\nwhich lead to division by zero.\n\nNormally no im protocol has value 1 in the mask, so this combination is\nnot expected by driver. But these protocol values actually come from\nuserspace via Netlink interface (NFC_CMD_START_POLL operation). So a\nbroken or malicious program may pass a message containing a \"bad\"\ncombination of protocol parameter values so that dev->poll_mod_count\nis not incremented inside pn533_poll_create_mod_list(), thus leading\nto division by zero.\nCall trace looks like:\nnfc_genl_start_poll()\n nfc_start_poll()\n ->start_poll()\n pn533_start_poll()\n\nAdd poll mod list filling check.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."
