Status: ModifiedHigh (7.5)—
Severity7.5High · CVSS 3.0
Exploitation probability1.02 %higher than 63% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In heap of spaces.h, there is a possible out of bounds read due to improper input validation. This could lead to remote information disclosure when processing a proxy auto config file 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-117555811
