## AI overview

XCP-ng 8.3 LTS receives security and maintenance updates. The release fixes Linux kernel vulnerabilities in the control domain, including issues that could allow an unprivileged local user to gain root privileges, and rejects obsolete insecure OpenSSH clients. It also includes improvements for USB smartcard passthrough, QEMU memory mapping, UEFI booting and CPU limits, PXE booting, and dmidecode.

## Source excerpt

Security vulnerabilities have been identified and fixed in the Linux kernel used by XCP-ng's control domain (dom0). Additional lower-priority maintenance updates are included in this release alongside these security fixes.
