From mboxrd@z Thu Jan 1 00:00:00 1970 From: julien.grall@arm.com (Julien Grall) Date: Tue, 10 May 2016 15:40:31 +0100 Subject: [PATCH] arm64: cpuinfo: Missing NULL terminator in compat_hwcap_str Message-ID: <1462891231-17605-1-git-send-email-julien.grall@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The loop that browses the array compat_hwcap_str will stop when a NULL is encountered, however NULL is missing at the end of array. This will result to overrun until one NULL is found somewhere in the memory.
