Last modified Jun 17, 2026

CVE-2021-0547 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In onReceive of NetInitiatedActivity.java, there is a possible way to supply an attacker-controlled value to a GPS HAL handler due to a missing permission check. This could lead to local escalation of privilege that may result in undefined behavior in some HAL implementations with no additional execution privileges needed. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
