CVE-2022-49729

5.5 · MEDIUM
Published Feb 26, 2025 linux CWE-401 EPSS 0.26% (18th pctl)

Overview

CVE-2022-49729 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred

Similar to the handling of play_deferred in commit 19cfe912c37b

("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought

a patch might be needed here as well.

Currently usb_submit_urb is called directly to submit deferred tx

urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb

and cause memory leak.

Put those urbs in tx_anchor to avoid the leak, and also fix the error

handling.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
