CVE-2009-0835

19
FAUCET Score

CVE-2009-0835 describes a security bypass vulnerability in the Linux kernel's seccomp subsystem (kernel/seccomp.c) affecting versions 2.6.28.7 and earlier on x86_64 platforms with CONFIG_SECCOMP enabled. This flaw allows local users to bypass access restrictions by crafting syscalls that are misinterpreted due to improper handling of mixed 32-bit and 64-bit syscalls. Rated with a CVSS score of 3.6 (AV:L/AC:L/Au:N/C:P/I:P/A:N), it indicates a low-severity local attack requiring no authentication, with potential for partial confidentiality and integrity impact. While no active exploitation or Metasploit/Nuclei modules are reported, an exploit is available on ExploitDB, and there is minimal community discussion or media coverage surrounding this decade-old vulnerability.
