CVE-2009-0834 describes a vulnerability in the Linux kernel (versions 2.6.28.7 and earlier on x86_64 platforms) where the audit_syscall_entry function improperly handles mixed-mode syscalls (32-bit processes making 64-bit calls or vice-versa), affecting various Linux distributions including Canonical, Debian, and Red Hat. This allows local users to bypass syscall audit configurations. The vulnerability has a CVSS score of 3.6, indicating low severity with local access, low attack complexity, and potential for partial confidentiality and integrity impact. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
