CVE-2026-127099

Sssd: sssd: stack buffer overflow during rsa certificate-to-ssh key conversion

A flaw was found in SSSD's conversion of X.509 certificate RSA public keys to SSH keys. Missing size checks before copying RSA components into fixed-size stack buffers can cause a stack buffer overflow. An attacker able to supply a certificate with oversized RSA components that passes the configured certificate checks can cause denial of service and corrupt SSH responder memory.

Yggdrasil-worker-package-manager: yggdrasil-worker-package-manager: path traversal via unsanitized repo name in addrepo/removerepo

A flaw was found in yggdrasil-worker-package-manager. An authenticated attacker can exploit this issue to achieve arbitrary file modification or potential privilege escalation. The vulnerability exists because repository management operations fail to sanitize directory traversal sequences (such as '../') within repository names. By supplying a crafted repository name, an attacker can manipulate the root-level worker process into creating or deleting files outside the intended directory, compromising host system integrity.

CVE-2026-126644

Ansible.posix: authorized_key module follows a parent-directory symlink allowing writes outside the intended directory

A link-following flaw was found in the authorized_key module of the ansible.posix collection, residual to the fix for CVE-2026-11837. That fix guards only the final path component (os.chown with follow_symlinks=False and O_NOFOLLOW in _safe_open_write()). When an unprivileged local user replaces their ~/.ssh directory with a symlink to a directory they do not own, and an operator subsequently runs the authorized_key task as root (a common provisioning pattern), the module resolves its path operations through the symlink: atomic_move() writes the temporary file in the symlink target and renames it to <target>/authorized_keys, creating or overwriting a file in the attacker-chosen directory, and os.chmod(sshdir, 0o700) follows the symlink and changes the target directory's permissions. The written file is chowned to the unprivileged user, so this is not a privilege escalation, but it allows an attacker to create or overwrite files (for example in /etc/apt/apt.conf.d/, which APT reads regardless of file ownership) to cause integrity and availability impacts.
