CVE-2023-3090
What it is
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.
