Hi Steve,

I could not reproduce this issue. I tried qemux86-64, qemuarm and qemuarm64.
Could you please help check how to reproduce this issue?

Regards,
Qi

Here are the logs for the arm64 and x86-64 ptest runs with the failure:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/61/builds/1852/steps/12/logs/stdio
https://autobuilder.yoctoproject.org/valkyrie/#/builders/73/builds/1855/steps/12/logs/stdio

There should be enough info there to allow you to try to reproduce the issue.

I finally reproduced the issue. It's about valgrind. The test case could 
run with/without valgrind. With valgrind installed on target, valgrind 
is reporting error for coretuils's sort with/without this patch. I think 
valgrind in kirkstone might have some problem. I'll disable valgrind in 
the test case.

Regards,
Qi

+Subject: [PATCH] sort: fix buffer under-read (CWE-127)
+
+* src/sort.c (begfield): Check pointer adjustment
+to avoid Out-of-range pointer offset (CWE-823).
+(limfield): Likewise.
+* tests/sort/sort-field-limit.sh: Add a new test,
+which triggers with ASAN or Valgrind.
+* tests/local.mk: Reference the new test.
+* NEWS: Mention bug fix introduced in v7.2 (2009).
+Fixes https://bugs.gnu.org/78507
+
+CVE: CVE-2025-5278
+
+Upstream-Status: Backport [https://cgit.git.savannah.gnu.org/cgit/coreutils.git/commit/?id=8c9602e3a145e9596dc1a63c6ed67865814b6633]
