UBUNTU-CVE-2024-46676: Medium severity ubuntu/linux vulnerability

Q: Who can trigger the failure?

A local userspace program that can send the NFC_CMD_START_POLL Netlink operation can supply the malformed protocol parameter combination. The issue is in the pn533 NFC driver path.

Q: What input is required to exploit the issue?

The program must provide im_protocols with value 1 and tm_protocols with value 0. This passes the initial nonzero check but leaves the poll mode list empty, causing dev->poll_mod_count to remain zero and leading to division by zero.

Published Sep 13, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: Add poll mod list filling check In case of improtocols value is 1 and tmprotocols value is 0 this combination successfully passes the check 'if (!improtocols && !tmprotocols)' in the nfcstartpoll(). But then after pn533pollcreatemodlist() call in pn533startpoll() poll mod list will remain empty and dev->pollmodcount will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. But these protocol values actually come from userspace via Netlink interface (NFCCMDSTARTPOLL operation). So a broken or malicious program may pass a message containing a "bad" combination of protocol parameter values so that dev->pollmodcount is not incremented inside pn533pollcreatemodlist(), thus leading to division by zero. Call trace looks like: nfcgenlstartpoll() nfcstartpoll() ->startpoll() pn533startpoll() Add poll mod list filling check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Frequently Asked Questions

Who can trigger the failure?

A local userspace program that can send the NFC_CMD_START_POLL Netlink operation can supply the malformed protocol parameter combination. The issue is in the pn533 NFC driver path.

What input is required to exploit the issue?

The program must provide im_protocols with value 1 and tm_protocols with value 0. This passes the initial nonzero check but leaves the poll mode list empty, causing dev->poll_mod_count to remain zero and leading to division by zero.

Are normal NFC polling configurations expected to hit this condition?

No. The description states that no IM protocol normally has value 1 in the mask, so the triggering combination is not expected during normal driver use.
