Vetor base

AV:L/AC:L/Au:N/C:C/I:N/A:C

Name of the Vulnerable Software and Affected Versions: Linux kernel versions 2.6.20 and later

Description: The issue is related to an integer signedness error in the DCCP support within the Linux kernel. This error occurs in the do dccp getsockopt function in net/dccp/proto.c, allowing local users to potentially read kernel memory or cause a denial of service. The exploitation is possible via a negative optlen value.

Recommendations: For Linux kernel versions 2.6.20 and later, consider applying a patch that fixes the integer signedness error in the do dccp getsockopt function to prevent potential exploitation. As a temporary workaround, restrict access to the do dccp getsockopt function to minimize the risk of exploitation.
