Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs: dropping peer group IDs under namespace lock When cleaning up peer group IDs in the failure path, we need to ensure that the namespace lock is retained. Otherwise, another thread might simultaneously change the mount status...

CVE-2026-47107

Windmill prior to 1.703.2 contains an incorrect default permissions vulnerability in nsjail sandbox configuration files where /etc is bind-mounted without read-write restrictions, allowing authenticated users to write arbitrary entries to /etc/hosts, /etc/resolv.conf, and...

CVE-2026-4137

CVE-2026-4137 : In mlflow/mlflow before 3.11.0, two temp-dir creation paths expose world/group-writable permissions: get_or_create_nfs_tmp_dir() creates 0o777 and _create_model_downloading_tmp_dir() creates 0o770. This enables local attackers with access to shared NFS mounts (e.g., Databricks) to...

UNIX Symbolic Link (Symlink) Following

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following during docker cp mount setup before subsequent mount syscall. An attacker can overwrite arbitrary files on the host or cause denial of service by exploiting a race condition where a symlink is create...

Docker: Race condition in docker cp allows bind mount redirection to host path

Summary A race condition during docker cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path, potentially overwriting host files or causing denial of service. Details When copying files into a container, the daemon sets up a temporary filesystem vie...
