CVE-2010-0923

18
FAUCET Score

CVE-2010-0923 describes a race condition in the KRunner lock module within KDE SC 4.4.0, specifically in kdebase. This vulnerability allows a physically proximate attacker to bypass the KScreenSaver screen lock on an unattended workstation by precisely timing an Enter key press, due to issues with multiple forked processes. With a CVSS score of 6.9 (AV:L/AC:M/Au:N/C:C/I:C/A:C), it indicates high impact on confidentiality, integrity, and availability, but requires medium attack complexity and local access. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
