The patch titled
Subject: thermal: fix potential out-of-bounds memory access
has been removed from the -mm tree. Its filename was
thermal-fix-potential-out-of-bounds-memory-access.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Guenter Roeck <linux@xxxxxxxxxxxx>
Subject: thermal: fix potential out-of-bounds memory access
temp_crit.name and temp_input.name have a length of 16 bytes. Using
THERMAL_NAME_LENGTH (20) as length parameter for snprintf() may result in
out-of-bounds memory accesses. Replace it with sizeof().
Addresses Coverity #115679
