Note: It appears that the page frame itself was initialized. For debugging, I would suggest to invoke __msan_print_shadow(), as noted in the MemorySanitizer wiki page.
This probably affects earlier versions as well, but I do not think that we can get MSAN to work well before version 10.5.
As far as I can tell, the server could crash in buf_LRU_block_remove_hashed() if a ROW_FORMAT=COMPRESSED page has a page checksum failure. As a fix, we will zero-fill the uncompressed page frame.
