CVE-2009-0676

Publication date 22 February 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The sock_getsockopt function in net/core/sock.c in the Linux kernel before 2.6.28.6 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request.

From the Ubuntu Security Team

The getsockopt function did not correctly clear certain parameters. A local attacker could read leaked kernel memory, leading to a loss of privacy.
