Description

An unprivileged application can bypass the `android.car.permission.CAR_DISPLAY_IN_CLUSTER` permission by registering an activity with the `android.car.cluster.NAVIGATION` category and requesting navigation app focus. The privileged `ClusterHomeSample` application, acting as a confused deputy, resolves and launches this arbitrary third-party activity on the safety-critical instrument cluster display without enforcing the necessary permission check, allowing for persistent display of potentially misleading or distracting content.

CVE-2026-29508

ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 contain a stack-based buffer overflow vulnerability that allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value that is used unvalidated to allocate a variable-length stack array and read file data into it. Attackers can place a crafted DFF file in a directory monitored by ReadyMedia to trigger automatic parsing via inotify, achieving remote code execution on unprotected builds or denial of service on hardened builds with stack protections.

CVE-2026-58915

A physical occupant on an Android Automotive OS (AAOS) Multi-User Multi-Display (MUMD) passenger display can view sensitive Heads-Up Notification (HUN) content and execute actions for a secure passenger user (User N) without authenticating. This bypasses the PassengerKeyguard because the HUN system only checks the global keyguard state, which is tied to the driver's unlocked display, and the PassengerKeyguard implementation fails to suppress HUNs or intercept action PendingIntents. Consequently, private notification data is disclosed, and user-N actions are executed without credential verification.
