CVE-2017-1000251

Published: 12 September 2017

The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space.

From the Ubuntu security team

It was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash).

Priority

High

CVSS 3 base score: 8.0

Notes

AuthorNote
sbeattie
stack-based buffer overflow; stack-protector kernel
configuration should result in this being limited to a remote
denial of service.
initial report claimed introduced in 0e8b207e8a44, but
possible vuln code path introduced in f2fcfcd67
cloudy kernels are much lower priority, since they typically
don't have bluetooth as a threat.
