Summary
CVE-2025-48630 is a high-severity Observable Timing Discrepancy (CWE-208) vulnerability in Google Android. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 0.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 PE-19 (Information Leakage) and SC-31 (Covert Channel Analysis).
Deeper analysis
CVE-2025-48630 is a side-channel information disclosure vulnerability located in the drawLayersInternal function of SkiaRenderEngine.cpp. It enables unauthorized access to the GPU cache. This issue affects the Android platform, as evidenced by its inclusion in the Android security bulletin.
A local attacker can exploit this vulnerability without requiring additional execution privileges or user interaction. Exploitation involves high attack complexity due to the side-channel nature (CWE-208). Successful attacks lead to local escalation of privilege, with high impacts on confidentiality, integrity, and availability, as scored at 7.4 (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
The Android security bulletin published on March 1, 2026, at https://source.android.com/docs/security/bulletin/2026/2026-03-01 details patches and mitigation guidance for this vulnerability.

Directly requires analysis and mitigation of covert/side channels that could leak GPU cache contents, exactly matching the Skia drawLayersInternal flaw.
Mandates controls to stop information leakage from shared hardware resources such as the GPU cache exploited by this local side-channel attack.
Requires the system to prevent unintended information transfer through shared system resources, directly applicable to unauthorized GPU cache access.
