There is a heap-based buffer-overflow at generator_spgemm_csc_reader.c (function libxsmm_sparse_csc_reader) in LIBXSMM 1.10, a different vulnerability than CVE-2018-20541 (which is in a different part of the source code and is seen at a different address).
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
