CVE-2011-1478

Publication date 25 July 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The napi_reuse_skb function in net/core/dev.c in the Generic Receive Offload (GRO) implementation in the Linux kernel before 2.6.38 does not reset the values of certain structure members, which might allow remote attackers to cause a denial of service (NULL pointer dereference) via a malformed VLAN frame.

From the Ubuntu Security Team

Ryan Sweat discovered that the GRO code did not correctly validate memory. In some configurations on systems using VLANs, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service.
