In the Linux kernel, the following vulnerability has been resolved: net: ethernet: lantiq_etop: fix memory disclosure When applying padding, the buffer is not zeroed, which results in memory disclosure. The mentioned data is observed on the wire. This patch uses skb_put_padto() to pad Ethernet frames properly. The mentioned function zeroes the expanded buffer. In case the packet cannot be padded it is silently dropped. Statistics are also not incremented. This driver does not support statistics in the old 32-bit format or the new 64-bit format. These will be added in the future. In its current form, the patch should be easily backported to stable versions. Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets in hardware, so software padding must be applied.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7166-2 advisory.

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-49997 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: net: ethernet: lantiq_etop: fix memory     disclosure When applying padding, the buffer is not zeroed, which results in memory disclosure. The     mentioned data is observed on the wire. This patch uses skb_put_padto() to pad Ethernet frames properly.
    The mentioned function zeroes the expanded buffer. In case the packet cannot be padded it is silently     dropped. Statistics are also not incremented. This driver does not support statistics in the old 32-bit     format or the new 64-bit format. These will be added in the future. In its current form, the patch should     be easily backported to stable versions. Ethernet MACs on Amazon-SE and Danube cannot do padding of the     packets in hardware, so software padding must be applied. (CVE-2024-49997)
