CVE-2018-9518

Published: 10 September 2018

In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-73083945.

From the Ubuntu security team

It was discovered that a buffer overflow existed in the NFC Logical Link Control Protocol (llcp) implementation in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
