CVE-2023-3090

Out-of-bounds write in Linux kernel's ipvlan network driver

Published Jun 28, 2023 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
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.
