Validate that both string section headers are of type SHT_STRTAB before caching them.How do you think about to add any tags (like “Fixes” and “Cc”) accordingly?
Thanks for the suggestion. I can't seem to find any relevant commit
for Fixes. There are
ec2a29593c83e ("module: harden ELF info handling") and potentially
3c5700aeabd87 ("module: Factor out elf_validity_cache_secstrings")
Both of these commits already intended to harden the parsing. I don't
think there is any regression here.
As for Cc:, I can't think of anyone who should be explicitly added. If
you have any suggestions, please chime in.
