Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987040)
medium Nessus Plugin ID 268541
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987040 advisory.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.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel package.See Also
