Qubes OS 4.3.2-rc1 has been released for testing, featuring an upgrade to the default Fedora template to version 44 and a kernel update to Linux 7.2, with a stable release expected by the end of September. This release is primarily aimed at testers and includes two significant security fixes addressing vulnerabilities in qvm-open-in-vm and qvm-copy-to-vm. Users are advised to back up their systems before testing, as the release is not intended for production environments. The testing process will help validate the changes and ensure stability before the final version is launched

Qubes OS 4.3.2-rc1 Now Available for Testing with Fedora 44 and Linux 7.2

Qubes OS 4.3.2-rc1 shipped as a patch release, upgrading the default template to Fedora 44 and the kernel to Linux 7.2. The team expects a stable build by end of September without a second RC, calling the changes "relatively minor." Notably, the batch bundles two real security fixes: QSB-119 format string exploitation in qvm-open-in-vm and QSB-118 dom0 code execution in qvm-copy-to-vm. It's meant for testers and reinstallers rather than production systems, and users should make a full backup before jumping in.
