Base vector

AV:L/AC:L/PR:L/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 an out-of-bounds write in the ashmem ioctl function of ashmem.c. This is due to insufficient locking when accessing asma, which could lead to a local elevation of privilege. This enables code execution as a privileged process without needing additional execution privileges. User interaction is not required for exploitation.

Recommendations: For Android kernel, apply the necessary patch to fix the out-of-bounds write issue in the ashmem ioctl function.
