Description

A Use-After-Free (UAF) vulnerability exists in the EVS HAL, allowing a privileged client to free a `buffer_handle_t` while the producer thread is still using it. This race condition, triggered via `doneWithFrame` and `setMaxFramesInFlight`, enables an attacker to manipulate freed heap memory, potentially leading to the leakage of file descriptors from the EVS HAL process.

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-2026-49906

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.
