Subject: [PATCH] arm64: cpuinfo: Missing NULL terminator in compat_hwcap_str
Date: Tue, 10 May 2016 15:40:31 +0100 [thread overview]
Message-ID: <1462891231-17605-1-git-send-email-julien.grall@arm.com> (raw)
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.
Fixes: 44b82b7700d0 "arm64: Fix up /proc/cpuinfo"
