11
FAUCET Score

CVE-2014-9419 is a local information disclosure vulnerability affecting the Linux kernel (through version 3.18.1), specifically within the __switch_to function. This flaw allows local users to bypass Address Space Layout Randomization (ASLR) by reading a Thread Local Storage (TLS) base address due to improper loading of TLS descriptors. Rated with a CVSS score of 2.1 (low severity), it requires local access and has a low attack complexity, with the primary impact being confidentiality compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
