Overview

CVE-2022-48794 is a medium-severity vulnerability. It was published on July 16, 2024 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:

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
