CVE-2026-92162 Flatpak vulnerable to path traversal via unvalidated "arch" parameter in DeployAppstream

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. Prior to version 1.18.1, on systems where at least one OCI remote is configured most common on Fedora systems, a malicious local user in an active local session could use a crafted architecture na...

CVE-2026-92162

The Flatpak application deployment framework is vulnerable to a path traversal vulnerability in the DeployAppstream D-Bus method. The issue stems from the flatpak-system-helper process failing to validate the arch parameter, allowing a malicious local user to supply ../ components. This can trick...

CVE-2026-112939

filelock is a platform-independent file lock for Python. From 3.22.0 until 4.2.1, SoftFileLock can trust a forged process identifier in a marker that an attacker can modify but cannot remove, allowing an authorized contender such as another process of the holder's account or root to act as a...

CVE-2026-112937

filelock is a platform-independent file lock for Python. From 4.1.0 until 4.2.1, ReadWriteLock can remove a randomized .filelock- private-hard-link directory during cleanup, allowing another local user with rename access in a non-sticky parent to observe a live name or forge a dead-owner sweep na...

CVE-2026-112937

The filelock Python library, a platform-independent file lock, is vulnerable in versions 4.1.0 through 4.2.0 . The ReadWriteLock component can remove a randomized .filelock-* private-hard-link directory during cleanup. A local user with rename access in a non-sticky parent directory can exploit t...

CVE-2026-112936 filelock: ReadWriteLock follows a symlink at the lock path into SQLite

filelock is a platform-independent file lock for Python. From 3.20.4 until 4.0.9, ReadWriteLock and AsyncReadWriteLock versions from 3.20.4 resolve the lock path and pass it to SQLite without rejecting a final symbolic link, allowing another local user who can create names in the lock directory t...

CVE-2026-112935

filelock is a platform-independent file lock for Python. From 3.22.0 until 4.2.1, SoftFileLock can break a stale marker after an attacker frees its own marker following the stale read, an honest contender creates a live successor on the reused inode, and the successor's modification time is not...
