[PATCH 4.14 190/293] nfc: fix potential illegal memory access

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yang Wei <albin_yang@xxxxxxx>

[ Upstream commit dd006fc434e107ef90f7de0db9907cbc1c521645 ]

The frags_q is not properly initialized, it may result in illegal memory
access when conn_info is NULL.
The "goto free_exit" should be replaced by "goto exit".
