In the Linux kernel, the following vulnerability has been resolved:
kunit: executor: Fix a memory leak on failure in kunit_filter_tests
It's possible that memory allocation for 'filtered' will fail, but for the
copy of the suite to succeed. In this case, the copy could be leaked.
Properly free 'copy' in the error case for the allocation of 'filtered'
failing.
Note that there may also have been a similar issue in
kunit_filter_subsuites, before it was removed in "kunit: flatten
kunit_suite*** to kunit_suite** in .kunit_test_suites".
