SubjectRe: [PATCH] ipv6_sockglue: Fix a missing-check bug in ip6_ra_control()
From: Gen Zhang <>
Date: Fri, 24 May 2019 11:19:46 +0800

> In function ip6_ra_control(), the pointer new_ra is allocated a memory
> space via kmalloc(). And it is used in the following codes. However,
> when there is a memory allocation error, kmalloc() fails. Thus null
> pointer dereference may happen. And it will cause the kernel to crash.
> Therefore, we should check the return value and handle the error.
