Thanks for testing this. I've posted a patch set that should fix both of those issues: https://sourceware.org/pipermail/elfutils-devel/2025q3/008572.html I don't fully understand why this fixes the invalid read in https://issues.oss-fuzz.com/issues/440177309 but with the patch set applied valgrind reports no errors for both reproduces.
