CVE-2010-4346

14
FAUCET Score

CVE-2010-4346 describes a vulnerability in the Linux kernel (before 2.6.37-rc6) where the install_special_mapping function fails to call security_file_mmap, allowing local users to bypass mmap_min_addr restrictions. This could lead to NULL pointer dereference attacks. The vulnerability has a low severity (CVSS 2.1) with local access required and no impact on confidentiality or availability, only integrity. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
