Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net: core: reject skb_copy(_expand) for fraglist GSO skbs
SKB_GSO_FRAGLIST skbs must not be linearized, otherwise they become
invalid. Return NULL if such an skb is passed to skb_copy or
skb_copy_expand, in order to prevent a crash on a potential later
call to skb_gso_segment.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: core: rechazar skb_copy(_expand) para fraglist GSO skbs Los skbs SKB_GSO_FRAGLIST no deben linealizarse; de lo contrario, dejarán de ser válidos. Devuelve NULL si dicho skb se pasa a skb_copy o skb_copy_expand, para evitar un bloqueo en una posible llamada posterior a skb_gso_segment.
