| Doc Text: |
A flaw was found in the enic driver of the Linux kernel. The `enic_set_vf_port` function incorrectly assumes specific lengths for certain netlink (nl) attributes, such as `IFLA_PORT_PROFILE`, `IFLA_PORT_INSTANCE_UUID`, and `IFLA_PORT_HOST_UUID`. Due to insufficient validation of these attribute lengths, a local attacker could provide malformed input, leading to an out-of-bounds read access during memory copy operations. This could result in information disclosure or a denial of service.
