Description

This security bulletin contains information about 1 vulnerability.

1) Out-of-bounds read (CVE-ID: CVE-2026-46532)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote user to disclose limited sensitive information and cause a denial of service.

The vulnerability exists due to out-of-bounds read in the BlueDroid AVRCP vendor-command parser when processing a malformed AVRCP vendor command with a zero-length payload. A remote user can send a specially crafted AVRCP vendor command to disclose limited sensitive information and cause a denial of service.

Only builds with BlueDroid Classic Bluetooth and AVRCP target support enabled are vulnerable, and exploitation requires an established A2DP/AVRCP connection.

Remediation

Install update from vendor's website.
