Base vector

AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Android version Android-11

Description: In the phNxpNciHal print res status function of phNxpNciHal.cc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege in the NFC server with System execution privileges needed. User interaction is not needed for exploitation.

Recommendations: For Android version Android-11, consider restricting access to the NFC server to minimize the risk of exploitation until a patch is available. As a temporary workaround, disabling the phNxpNciHal print res status function in phNxpNciHal.cc may help mitigate the issue.
