**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue arises when a packet type is unknown to the driver, causing `idpf rx process skb fields` to return early without calling `eth type trans` to set the skb protocol or the network layer handler. This is particularly problematic if `tcpdump` is running when such a packet is received, as it would cause a kernel panic. To resolve this, `eth type trans` should be called for every single packet, even when the packet type is unknown. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
