Fixed In Version: kernel 6.4-rc2
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the IPVLAN network driver in the Linux kernel. This issue is caused by missing skb->cb initialization in `__ip_options_echo` and can lead to an out-of-bounds write stack overflow. This may allow a local user to cause a denial of service or potentially achieve local privilege escalation.

Description Guilherme de Almeida Suckevicz 2023-06-29 19:34:24 UTC 
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.
