Is my proxmox vulnerable

[delta-whiplash]

hello I have multiples proxmox nodes running on 6.5.13-1-pve, 6.5.13-3-pve, 6.5.13-5-pve

Am I vulnerable to this exploit ?

You have n_gsm driver ? Unprivileged user have access to clone userns?

[YuriiCrimson]

And you have xen support?

[delta-whiplash]

am not using xen (my proxmox servers are kvm/lxc only) how can I check if I have the n_gsm driver do I have to check if the n_gsm driver is in my proxmox host ? in my VM ? or in my LXC ?

@delta-whiplash you can grep /boot/config* for GSM and if you have not n, and the N_GSM module is not blacklisted you are likely to have a problem if you have local users that you do not trust.
