glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive

A flaw was found in GLib. The D-Bus client-side implementation of the DBUSCOOKIESHA1 SASL authentication mechanism does not validate the cookiecontext parameter received from the server. A malicious D-Bus server can supply a cookiecontext containing path traversal sequences, causing the client to...

CVE-2026-78422

Subject::newforowner in the zbuspolkit crate encodes the uid entry of a unix-process polkit subject as an unsigned 32-bit integer D-Bus type u, whereas the org.freedesktop.PolicyKit1.Authority interface specifies a signed 32-bit integer D-Bus type i. Because of this type mismatch, polkit silently...

CVE-2026-78422 zbus_polkit: polkit authorization bypass via PID reuse due to incorrect D-Bus type for the subject UID

Subject::newforowner in the zbuspolkit crate encodes the uid entry of a unix-process polkit subject as an unsigned 32-bit integer D-Bus type u, whereas the org.freedesktop.PolicyKit1.Authority interface specifies a signed 32-bit integer D-Bus type i.

CVE-2026-78422

CVE-2026-78422 affects the zbus_polkit Rust crate (before 5.1.0 ). The function Subject::new_for_owner() encodes the UID of a unix-process polkit subject as an unsigned 32-bit integer (D-Bus type u), while the org.freedesktop.PolicyKit1.Authority interface expects a signed 32-bit integer (type i)...

USN-8701-1 udisks2 vulnerability

It was discovered that UDisks did not correctly validate the caller identity when handling the as-user option in the org.freedesktop.UDisks2.Filesystem.Mount D-Bus method. A local attacker with an active console session could possibly use this issue to mount filesystems on behalf of arbitrary...

SUSE CVE-2026-54229

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DDOPENREADONLY and calls ddchown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows ...
