Technical Summary
CVE-2026-46532 is an out-of-bounds read vulnerability (CWE-125) found in the BlueDroid AVRCP vendor-command parser function avrc_pars_vendor_cmd() within the Espressif esp-idf IoT development framework. The affected versions are 5.2.6, 5.3.5, 5.4.4, 5.5.3, and 6.0. This vulnerability allows an attacker with local access to cause a read beyond the intended buffer boundaries, potentially leading to information disclosure or application instability. The issue has been patched in versions 5.2.7, 5.3.6, 5.4.5, 5.5.4, and 6.0.1.
Potential Impact
The vulnerability can lead to a low confidentiality impact due to out-of-bounds read, and a low availability impact due to potential application instability or crashes. There is no impact on integrity. The attack vector is adjacent (AV:A), requiring low attack complexity and low privileges with no user interaction needed.
Mitigation Recommendations
A fix is available and users should upgrade to esp-idf versions 5.2.7, 5.3.6, 5.4.5, 5.5.4, or 6.0.1 to remediate this vulnerability. Patch status is confirmed by the vendor's versioning information. No additional mitigation steps are indicated.
