 Package : lxd CVE ID : CVE-2026-9639 CVE-2026-9640 CVE-2026-48749 CVE-2026-48750 CVE-2026-48751 CVE-2026-48752 CVE-2026-48755 CVE-2026-48769 CVE-2026-55621 CVE-2026-55622

 Multiple security issues were discovered in LXD, a system container and virtual machine manager, which could result in a bypass of security restrictions or the execution of arbitrary commands.

 For the stable distribution (trixie), these problems have been fixed in version 5.0.2+git20231211.1364ae4-9+deb13u7.

 We recommend that you upgrade your lxd packages.

 For the detailed security status of lxd please refer to its security tracker page at:
