Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a memory leak in the Linux kernel's net component, specifically in the ieee802154: at86rf230 module. When an error occurs, the
ieee802154 xmit complete() helper is not called, resulting in a leak of the skb structure. To fix this, the skb structure is freed upon error before returning. An intermediate was tx boolean is introduced to handle a possible race between the delay in switching to STATE RX AACK ON and a new interrupt.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
