Subject: [PATCH -next v2 0/2] jffs2: fix two memory leak when mount jffs2
Date: Thu, 13 Jan 2022 15:48:46 +0800 [thread overview]
Message-ID: <20220113074848.1308414-1-libaokun1@huawei.com> (raw)
V1->V2:
In jffs2_scan_medium,
if s = kzalloc(sizeof(struct jffs2_summary), GFP_KERNEL);
returns error, go to "out" to do clear. Null pointer dereference
occurs when if (s->sum_list_head) is executed in "out".
