      <title>CVE-2026-81508 — ESF-IDF: Heap Out-of-Bounds Read in Bluedroid A2DP Sink Media Packet Processing</title>
      <link>https://db.gcve.eu/vuln/cve-2026-81508</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; espressif esp-idf&lt;/p&gt;
&lt;p&gt;ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In 5.5.5, 6.0.1, and 6.1, the BlueDroid A2DP sink function btc_a2dp_sink_handle_inc_media() reads a timestamp field from the received media buffer before validating that the packet layout contains the field. A paired BR/EDR audio source within radio range can send a malformed A2DP media packet to a build with BlueDroid Classic Bluetooth and A2DP sink support enabled, causing an out-of-bounds read into adjacent heap memory and limited disclosure of heap contents. Arbitrary memory disclosure and code execution are not established.&lt;/p&gt;</description>
