Until a fix is available, restrict local user access to the guest environment and limit use of external management layers that invoke the guest-ssh-add-authorized-keys command handler.
Description
A vulnerability in the QEMU Guest Agent (qga) allows a local unprivileged user to exploit the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can be done via a deterministic directory-symlink bypass or a TOCTOU file-symlink race, potentially leading to ownership of arbitrary root-owned files or directories and resulting in root access. Exploitation requires an external management layer such as libvirt to trigger the vulnerable code path.
