What is CVE-2022-32742?

A flaw exists in Samba where some SMB1 write requests lack sufficient range-checking, which enables server memory to potentially overwrite files or printer data. This vulnerability allows incorrect data to be written, as the client cannot dictate the memory area that is affected. Consequently, server memory contents may be unintentionally exposed or altered, posing significant security risks.
