Summary
EDAC/thunderx: Fix possible out-of-bounds string access
Details

In the Linux kernel, the following vulnerability has been resolved:

EDAC/thunderx: Fix possible out-of-bounds string access

Enabling -Wstringop-overflow globally exposes a warning for a common bug in the usage of strncat():

drivers/edac/thunderxedac.c: In function 'thunderxocxcomthreadedisr': drivers/edac/thunderxedac.c:1136:17: error: 'strncat' specified bound 1024 equals destination size [-Werror=stringop-overflow=] 1136 | strncat(msg, other, OCXMESSAGESIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ... 1145 | strncat(msg, other, OCXMESSAGESIZE); ... 1150 | strncat(msg, other, OCXMESSAGESIZE);

...

Apparently the author of this driver expected strncat() to behave the way that strlcat() does, which uses the size of the destination buffer as its third argument rather than the length of the source buffer. The result is that there is no check on the size of the allocated buffer.

Change it to strlcat().
