Descriptions

In the Linux kernel, the following vulnerability has been resolved:

phonet: fix rtm_phonet_notify() skb allocation

fill_route() stores three components in the skb:

- struct rtmsg
- RTA_DST (u8)
- RTA_OIF (u32)

Therefore, rtm_phonet_notify() should use

NLMSG_ALIGN(sizeof(struct rtmsg)) +
nla_total_size(1) +
nla_total_size(4)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phonet: corrige la asignación de skb de rtm_phonet_notify() fill_route() almacena tres componentes en el skb: - struct rtmsg - RTA_DST (u8) - RTA_OIF (u32) Por lo tanto, rtm_phonet_notify() debería usar NLMSG_ALIGN(tamañode(struct rtmsg)) + nla_total_size(1) + nla_total_size(4)
