CVE-2016-4580 (retired)

Priority
Description
The x25_negotiate_facilities function in net/x25/x25_facilities.c in the
Linux kernel before 4.5.5 does not properly initialize a certain data
structure, which allows attackers to obtain sensitive information from
kernel stack memory via an X.25 Call Request.
Ubuntu-Description
Kangjie Lu discovered an information leak in the X.25 Call Request handling
in the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory.

  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 tyhicks> Marking as low due to X.25's lack of adoption
