CVE-2011-1748

Publication date 9 May 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The raw_release function in net/can/raw.c in the Linux kernel before 2.6.39-rc6 does not properly validate a socket data structure, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation.

From the Ubuntu Security Team

Oliver Hartkopp and Dave Jones discovered that the CAN network driver did not correctly validate certain socket structures. If this driver was loaded, a local attacker could crash the system, leading to a denial of service.
