| Subject: CVE-2023-52907: nfc: pn533: Wait for out_urb's completion in pn533_usb_send_frame() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nfc: pn533: Wait for out_urb's completion in pn533_usb_send_frame() |
| |
| Fix a use-after-free that occurs in hcd when in_urb sent from |
| pn533_usb_send_frame() is completed earlier than out_urb. Its callback |
| frees the skb data in pn533_send_async_complete() that is used as a |
| transfer buffer of out_urb. Wait before sending in_urb until the |
| callback of out_urb is called. To modify the callback of out_urb alone, |
| separate the complete function of out_urb and ack_urb. |
| |
| Found by a modified version of syzkaller. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
