CVE-2022-48248 is a vulnerability discovered in the audio service component affecting various Android devices and Unisoc chipsets. The vulnerability was disclosed on May 8, 2023, and involves a missing permission check that could potentially lead to local escalation of privilege (NVD). The affected systems include Android versions 10.0 through 13.0 and multiple Unisoc chipsets including S8000, SC7731E, SC9832E, SC9863A, T310, T606, T610, T612, T616, T618, T760, T770, and T820 (NVD).

The vulnerability is classified as a Missing Authorization issue (CWE-862) with a CVSS v3.1 base score of 7.8 (HIGH). The attack vector is local (AV:L), with low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The scope is unchanged (S:U), with high impacts on confidentiality (C:H), integrity (I:H), and availability (A:H) (NVD).

If exploited, this vulnerability could allow a local attacker to escalate privileges on the affected device without requiring additional execution privileges. This could potentially give an attacker elevated access to system resources and sensitive information (NVD).

Unisoc has released an advisory addressing this vulnerability. Users of affected devices should ensure their systems are updated with the latest security patches (Vendor Advisory).
