CVE-2018-20541
There is a heap-based buffer overflow in libxsmm_sparse_csc_reader at generator_spgemm_csc_reader.c in LIBXSMM 1.10, a different vulnerability than CVE-2018-20542 (which is in a different part of the source code and is seen at different addresses).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
