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.

Affected configurations

• linux linux kernel (>= 6.12.64 < 6.12.66) • linux linux kernel (>= 6.18.4 < 6.18.6) • linux linux kernel 6.1.160 • linux linux kernel 6.6.120 • linux linux kernel 6.19
