Local denial of service via unchecked GNSS write
Published Dec 4, 2023 · Updated Oct 11, 2024
Out-of-bounds write in the Unisoc GNSS service on Android 11 through 13 allows local users with System privileges to interrupt service. The GNSS service copies input into a memory buffer without checking its size, allowing the write to exceed the destination's bounds. Exploitation requires local execution with System privileges; the published consequence is denial of service rather than code execution.
