Title
EDAC/thunderx: Fix possible out-of-bounds string access
Summary
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/thunderx_edac.c: In function 'thunderx_ocx_com_threaded_isr':
drivers/edac/thunderx_edac.c:1136:17: error: 'strncat' specified bound 1024 equals destination size [-Werror=stringop-overflow=]
1136 | strncat(msg, other, OCX_MESSAGE_SIZE);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...
1145 | strncat(msg, other, OCX_MESSAGE_SIZE);
...
1150 | strncat(msg, other, OCX_MESSAGE_SIZE);
...
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().
[ bp: Trim compiler output, fixup commit message. ]

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
