CVE-2011-1478

CVE Details

Release Date:2011-10-23

Description


The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. 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.
