CVE-2020-0143

Status: ModifiedMedium (4.4)—

In nfa_dm_ndef_find_next_handler of nfa_dm_ndef.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure of heap data via compromised device firmware with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-145597277

CVSS
