Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987534)

medium Nessus Plugin ID 270893

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-2025-987534 advisory.

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

 net: ieee802154: at86rf230: Stop leaking skb's

 Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. In the Tx case we then leak the skb structure.

 Free the skb structure upon error before returning when appropriate.

 As the 'is_tx = 0' cannot be moved in the complete handler because of a possible race between the delay in switching to STATE_RX_AACK_ON and a new interrupt, we introduce an intermediate 'was_tx' boolean just for this purpose.

 There is no Fixes tag applying here, many changes have been made on this area and the issue kind of always existed.

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.
