CVE-2024-46676 is a medium severity vulnerability in the Linux kernel's NFC driver for the PN533 chip. It involves a division by zero error triggered when a specific combination of protocol values is passed from userspace via the Netlink interface. This occurs because the poll mod list remains empty and the poll mod count remains zero, leading to a division by zero in the pn533_start_poll() function. The issue was discovered by the Linux Verification Center and has been addressed by adding a check to ensure the poll mod list is properly filled.
