MediumMetricsAV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions
Android kernel
Description
The issue is related to a possible out of bounds write due to a missing bounds check in
ProtocolCallBuilder::BuildSendUssd of protocolcallbuilder.cpp. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Recommendations
For Android kernel, consider applying a patch that includes a bounds check in the
ProtocolCallBuilder::BuildSendUssd function to prevent out of bounds writes. As a temporary workaround, restrict access to the BuildSendUssd function to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
