NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-devel package and not the kernel-zfcpdump-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.

The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.

We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.
