Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds write in the Parse of simdata.cpp due to a missing bounds check. 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 simdata.cpp Parse function to prevent out of bounds writes. As a temporary workaround, restrict access to the simdata.cpp module to minimize the risk of exploitation.
