Background

The net: ieee802154: ca8210 package is a component of the Linux Kernel. It provides support for the CA8210 IEEE 802.15.4 radio transceiver. This package allows communication over low-power wireless networks. The vulnerability in this package involves the leaking of skb's, which are socket buffers used for network communication. This can lead to potential security risks if sensitive information is exposed.

Vulnerability Detail

The vulnerability in the net: ieee802154: ca8210 package involves the leaking of skb's. When skb's are not properly handled, they can be leaked, potentially exposing sensitive information. This vulnerability was introduced in version v4.12 of the Linux Kernel and was fixed in version v4.19.228. The impact and attack plausibility of this vulnerability have not been proven yet.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v4.19.228 or later. This can be done by pulling the latest updates from the official Linux Kernel repository.
