CVE-2024-26803

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The vulnerability is related to the Linux kernel's virtual Ethernet (veth) component. When XDP (eXpress Data Path) is enabled, veth sets the NETIF F GRO flag automatically because both features use the same NAPI machinery. However, the logic to clear this flag is skipped when the device is brought down, which can lead to a stray GRO flag being set when XDP is disabled and then the device is brought up. This can cause the system to crash or hang when features are synchronized, either by the user via ethtool or by a peer changing its configuration.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
