21
FAUCET Score

CVE-2010-2066 describes a vulnerability in the Linux kernel (before 2.6.35) affecting Canonical, SUSE, and VMware, where a local user can overwrite an append-only file using a MOVE_EXT ioctl call. This medium-severity vulnerability (CVSS 5.5) has a low attack complexity and requires local user privileges, potentially leading to high integrity impact but no confidentiality or availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
