CVE-2017-12762

Published: 9 August 2017

In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. This affects the Linux kernel 4.9-stable tree, 4.12-stable tree, 3.18-stable tree, and 4.4-stable tree.

From the Ubuntu security team

It was discovered that a buffer overflow existed in the ioctl handling code in the ISDN subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Priority

Medium

CVSS 3 base score: 9.8
