CVE-2022-32742 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. EPSS estimates a 1.00% chance of exploitation in the next 30 days.
