The vulnerability was disclosed and published in the National Vulnerability Database (NVD) on May 8, 2023. It affects multiple versions of Android (10.0 through 13.0) running on various UNISOC chipset models including S8000, SC7731E, SC9832E, SC9863A, T310, T606, T610, T612, T616, T618, T760, T770, and T820 (NVD).

The vulnerability is characterized as a missing permission check in the audio service component. According to the NVD assessment, it received a CVSS v3.1 base score of 7.8 (HIGH), with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This scoring indicates that the vulnerability requires local access, low attack complexity, low privileges, and no user interaction, while potentially impacting confidentiality, integrity, and availability at high levels (NVD).

If exploited, this vulnerability could lead to local escalation of privilege with no additional execution privileges needed. This means an attacker who successfully exploits this vulnerability could gain elevated access to system resources that should normally be protected (NVD).

UNISOC has released an advisory addressing this vulnerability. Users and administrators are advised to apply any security updates provided by their device manufacturers that include fixes for this vulnerability (Vendor Advisory).
