| Vector | AV:L/AC:M/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.4.8
Description
The issue allows local users to cause a denial of service, resulting in a system crash due to a NULL pointer dereference. This is achieved through an IPOPT CIPSO IP OPTIONS setsockopt system call. The
cipso v4 validate function in net/ipv4/cipso ipv4.c is the vulnerable component.Recommendations
For Linux kernel versions prior to 3.4.8, update to version 3.4.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the
setsockopt system call to minimize the risk of exploitation.Fix
