CVE-2014-3153: Linux Kernel Privilege Escalation Vulnerability

76

Urgent

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

CISA KEV · May 25, 2022 Metasploit modules · 1 Exploit-DB · 1

How the score was calculated

Confirmed exploitation (CISA KEV)+35
Public exploit/PoC (metasploit, exploitdb)+20
EPSS 37.2% (30-day exploitation probability)+15
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

US federal deadline: Jun 15, 2022 — passed 1583 day(s) ago

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Canonical Ubuntu Linux, Linux Linux Kernel, Opensuse Opensuse…).
Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
Apply the fixed version or the patch documented under Remediation.
EPSS ahead of 99% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes, errors and authentication anomalies.

CISA KEV details CISA

CISA lists a CVE once it has evidence of exploitation against real targets.

Listed

May 25, 2022

Federal deadline

Jun 15, 2022

passed 1583 day(s) ago

Ransomware use

Unknown

CISA records ransomware use only for campaigns it has confirmed, so “Unknown” means unrecorded, not ruled out. The deadline binds US federal agencies; for everyone else it is a reference date.

Public exploits, PoCs and detection templates

Public code that demonstrates or tests the flaw raises the odds of mass exploitation — and Nuclei templates help find vulnerable assets in your environment.

Metasploit modules

Exploit-DB

Warning: public PoCs are sometimes disguised malware. Use them only for authorized testing in an isolated environment. This portal does not host exploit code — it only points to the sources.

What should defenders know first?

CVE-2014-3153 is "Linux Kernel Privilege Escalation Vulnerability", rated High. It affects Ubuntu Linux (Canonical); versions are in the scope table. It is in CISA KEV: there is evidence of real-world exploitation. CVSS 7.8 describes technical severity. EPSS 37.23% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
