CVE-2017-15868
Publication date 5 December 2017
Last updated 24 July 2024
Ubuntu priority
The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.
From the Ubuntu Security Team
It was discovered that the Bluebooth Network Encapsulation Protocol (BNEP) implementation in the Linux kernel did not validate the type of socket passed in the BNEPCONNADD ioctl(). A local attacker with the CAP_NET_ADMIN privilege could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
