FAUCET Score

CVE-2009-3612 is a Linux kernel information disclosure vulnerability affecting versions 2.6.x before 2.6.32-rc5 and 2.4.37.6 and earlier, including distributions like Canonical, Fedora, openSUSE, and SUSE. It stems from an uninitialized structure member in the netlink subsystem, potentially allowing local users to leak sensitive kernel memory.

There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
