CVE-2014-5207

Status: ModifiedMedium (6.2)—💥 Exploit

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.

CVSS

Version: 2.0
Vector: AV:L/AC:H/Au:N/C:C/I:C/A:C
Base score: 6.2

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.88%
Percentile among all scored CVEs: 58
Score date: 10/13/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
