CVE-2015-2830

11
FAUCET Score

CVE-2015-2830 describes a flaw in the Linux kernel (before version 3.19.2) where the TS_COMPAT flag could be exposed to user-mode tasks, potentially allowing local users to bypass security mechanisms like seccomp or auditing. This vulnerability primarily affects various distributions of Linux, including Canonical and Debian. With a low CVSS score of 1.9, it requires local access and medium attack complexity, leading to a potential impact of information disclosure (I:P) rather than integrity or availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
