CVE-2019-2053

Published: 8 May 2019

In wnm_parse_neighbor_report_elem of wnm_sta.c, there is a possible out-of-bounds read due to missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android-7.0 Android-7.1.1 Android-7.1.2 Android-8.0 Android-8.1 Android-9 Android ID: A-122074159

Notes

AuthorNote
mdeslaur
per upstream: The actual read bytes would be stored locally,
but they were not used for anything, so other than reading
beyond the end of an allocated heap memory buffer, this did not
result in any behavior difference or exposure of the bytes.
