CVE-2026-1386 Arbitrary Host File Overwrite via Symlink in Firecracker Jailer

A UNIX symbolic link following issue in the jailer component in Firecracker version v1.13.1 and earlier and 1.14.0 on Linux may allow a local host user with write access to the pre-created jailer directories to overwrite arbitrary host files via a symlink attack during the initialization copy at...

CVE-2026-1386

The CVE-2026-1386 issue affects Firecracker’s jailer component. A local user who has write access to pre-created jailer directories could abuse a UNIX symlink vulnerability during jailer startup to overwrite arbitrary host files when the jailer runs with root privileges. Affected versions include...

runc: container escape with malicious config due to /dev/console mount and related races

A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console bind-mounts. When creating the /dev/console bind-mount to /dev/pts/$n, if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount...

runc: container escape via 'masked path' abuse due to mount race conditions

A flaw was found in runc. This flaw exploits an issue with how masked paths are implementedin runc. When masking files, runc will bind-mount the container's /dev/null inode on top of the file. However, if an attacker can replace /dev/null with a symlink to some other procfs file, runc will instea...
