Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds write due to an incorrect bounds check in the fillSetupDataCallInfo V1 6 function of ril service 1 6.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, apply the necessary patch to fix the incorrect bounds check in the fillSetupDataCallInfo V1 6 function of ril service 1 6.cpp. As a temporary workaround, consider restricting access to the ril service 1 6.cpp module to minimize the risk of exploitation.
