CVE-2026-22988
In the Linux kernel, the following vulnerability has been resolved: arp: do not assume dev_hard_header() does not change skb->head arp_create() is the only dev_hard_header() caller making assumption about skb->head being unchanged.
Does this matter?
Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: arp: do not assume dev_hard_header() does not change skb->head arp_create() is the only dev_hard_header() caller making assumption about skb->head being unchanged. A recent commit broke this assumption. Initialize @arp pointer after dev_hard_header() call.
