Detailsinfo

A vulnerability classified as very critical has been found in Google Android (the affected version unknown). Affected is an unknown part of the file bitmap_image_buffer.h of the component Trusted Execution Environment. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In multiple functions of bitmap_image_buffer.h, there is a possible way to trigger an out of bounds write on the trusted execution environment heap due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
