Cilium is open source software for providing and securing network connectivity and loadbalancing between application workloads. Cilium prior to versions 1.9.16, 1.10.11, and 1.11.15 contains an incorrect default permissions vulnerability. Operating Systems with users belonging to the group ID 1000 can access the API of Cilium via Unix domain socket available on the host where Cilium is running. This could allow malicious users to compromise integrity as well as system availability on that host. The problem has been fixed and the patch is available in versions 1.9.16, 1.10.11, and 1.11.5. A potential workaround is to modify Cilium's DaemonSet to run with a certain command, which can be found in the GitHub Security Advisory for this vulnerability.

Access to Unix domain socket can lead to privileges escalation in Cilium
### Impact
Users with host file system access on a node and the privileges to run as group ID 1000 can gain access to the per node API of Cilium via Unix domain socket on the host where Cilium is running. If a malicious user is able to gain unprivileged access to a user corresponding to this group, then they can leverage this access to compromise the integrity as well as system availability on that host. Operating Systems that have unprivileged users **not** belonging the group ID 1000 are **not** affected by this vulnerability.
Best practices for managing the secure deployment of Kubernetes clusters will typically limit the ability for a malicious user to deploy pods with access to this group or to access the host
