Status: ModifiedMedium (6.7)—

In lwis_buffer_alloc of lwis_buffer.c, there is a possible arbitrary code execution due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-209436980References: N/A
