Qubes OS 4.3.2 has been released as a patch build that includes all security fixes and bug corrections since version 4.3.1, featuring two critical code-execution fixes. The default Fedora template has been upgraded to Fedora 44, and the rolling kernel has been updated to Linux 7.2. Users still on Qubes 4.2 are strongly advised to upgrade, as that version has reached its end of life and no longer receives updates. The release addresses two vulnerabilities that could allow attackers to gain control of either a qube or the dom0 environment, and users can easily upgrade through the Qubes Update tool or by downloading the new ISO
