A flaw was found in NetworkManager-l2tp. The plugin writes attacker-controlled VPN connection properties vpn.data and vpn.secrets values unescaped into a generated ipsec.conf file that pluto loads as root. A local unprivileged user can create and activate their own L2TP VPN profile containing a...

EUVD-2026-78063

A flaw was found in PackageKit. PackageKit skips the polkit authorization check for transactions carrying the SIMULATE dry-run flag. In the dnf5 backend, the RepoRemove handler ignores that contract and always executes the real transaction because its guard is written as role == REPOREMOVE ||...

CVE-2026-19816 PackageKit: dnf5 backend ignores SIMULATE on RepoRemove

rsync: rsync: Local Privilege Escalation via Symlink Following

A symlink-following vulnerability in rsync allows local attackers to redirect predictable output paths to arbitrary filesystem locations. When rsync runs with elevated privileges such as setuid or a privileged daemon, this enables arbitrary file overwrites and local privilege escalation...

rsync: rsync: Arbitrary File Read via Symlink Following

A flaw was found in rsync. A local attacker with low privileges can exploit a symlink following vulnerability in the handling of input configuration files, such as those specified by --files-from or --password-file. This allows the attacker to read arbitrary files accessible to the rsync daemon...
