CVE-2015-5706

14
FAUCET Score

CVE-2015-5706 describes a use-after-free vulnerability in the Linux kernel (versions 3.x and 4.x before 4.0.4), specifically within the path_openat function, affecting various Canonical and Debian Linux distributions. This flaw allows a local attacker to trigger a denial of service or potentially achieve other unspecified impacts through O_TMPFILE filesystem operations that exploit a duplicate cleanup. With a CVSS score of 4.6, it is considered a low-severity vulnerability, requiring local access and low attack complexity, with potential for partial confidentiality, integrity, and availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating a low current threat level.
